Opis:
The design of the experimental laboratory device is based on the construction of the hydraulic circuits of mobile devices. It is possible to ensure the repeatability of the flow characteristic measurements at the laboratory. This means that in the operating test it is possible to verify the flow characteristics of the hydraulic pump and these results are not affected by the change in the physical properties of the applied liquid. By comparing of the flow characteristics directly on the work equipment (mini-excavator, etc.), the disadvantage is the need for dismantling the hydraulic pump and its mounting on the laboratory device. In some working device removal is not possible, where dismantling is structurally difficult or is time consuming, which increases the cost of their operation.The proposed experimental laboratory device serves to verify the flow characteristics of the hydraulic pump and is also designed to be universal, to test external gear hydraulic pump and hydraulic pump with inclined plate.

Opis:
The content of this article is a direct continuation of the prior experimental works on the topic of cloud cavitation in Venturis. The results of the experimental tests were used to create a set of characteristics for three types of Venturis. The article has two aims: 1) verification of the similarity between the characteristics obtained and reported in the literature, 2) verification of the range of the obtained characteristics with respect to parallel diagrams. Both aims were achieved, which confirms that the quality of the prior results of the experimental measurements is at least sufficient to realize the main objective of the whole project: creation of numerical models of cavitating flow in Venturis. The literature overview showed that the issue has been not solved until today, even at the qualitative level. This reason was the motivation for the undertaken research, including contents of the article.

Opis:
This paper describes the use of computational methods for solving the flow of the air-cooling in the large synchronous machines where it is used to cool the stator winding and stator radial channels which are located between the stator packet sheets. The overall process flow is mostly influenced by the size of air gap between stator and rotor, the shape of the radial channels, and by flow rates in machines. This paper mostly discusses about the influence flow rate of the cooling medium which has effects on the pressure distribution and flow rate in the radial channels. Cooling medium considered in this article an air and for and for calculation was chosen ANSYS CFX.

Opis:
In this paper the authors describe an attempt to utilise installed square- sectioned elbows in order to measure the fluid flow rate. In order to practically accomplish the measurement of the volumetric flow rate of the air, a special research stand has been built, and square shaped elbows have been installed (80 × 80mm in dimension). The numerical computations were carried out using the software package FLUENT 6.2. The obtained results were compared to corresponding ones coming from orifice measurements and from experimental work available in the literature. The comparative analysis of the obtained numerical and experimental results evidenced a high degree of their conformity.
W pracy podjęto próbę wykorzystania zainstalowanych w kanałach przepływowych łuków kolan o przekroju kwadratowym do pomiaru strumienia objętości płynu. W tym celu wykorzystano opracowaną wcześniej metodę pomiaru pośredniego dla rurociągów o przekroju kołowym. Dla praktycznej realizacji pomiaru wspomnianego strumienia przepływu zbudowano stanowisko badawcze za łukiem kolana o przekroju poprzecznym w kształcie kwadratu (80 × 80mm). Obliczenia wykonano za pomocą pakietu FLUENT 6.2. Uzyskane rezultaty porównano z odpowiednimi zmierzonymi za pomocą kryzy pomiarowej oraz z innymi wynikami doświadczalnymi dostępnymi w literaturze. Z analizy porównawczej wynika wysoki stopień zgodności otrzymanych rezultatów pomiaru pośredniego.

Opis:
The main purpose of the froth zone in flotation is to transport all the valuable particles from the pulp zone into the concentrate. However, in practice, a complete recovery of these particles is rarely achieved since some of them are detachment from the bubbles and return to the pulp zone. While this is an important topic in the mineral flotation industry, the previously published papers are mainly limited to small laboratory scales. Therefore, this study aimed to examine the effect of two main flotation variables (air flowrate and froth depth) on the flotation of iron ore in a 10 m3 industrial scale cell. It was found that, when the air flowrate increased from 45 to 146 m3/h, the velocity of the bubble coalescence also increased. In addition, when the froth depth increased from 5 to 30 cm, the product grade showed on average 2 unit increase (for instance, from 12% to 14%) due to the detachment of particles and liquid drainage. It was also found that the flotation concentrates recovery decreased with the increasing froth depth and air flowrate.

Opis:
Fast water flow facilitates ferrous ion transport leading to flow accelerated corrosion (FAC) of carbon steel and the possibility of a large accident through a failure of a secondary pipe in a nuclear power plant. Ion transport is directly linked to oxide properties such as the thickness, chemical composition and porosity. This work deals with a precise observation of the cross section of the corroded specimen focusing on an oxide passivity and its thickness using SEM (scanning electron microscope) and TEM (transmission electron microscope) as well as an apparent weight loss and a surface observation for the specimens corroded using a rotating cylindrical electrode autoclave system in pure water of pH 7 at 150°C having dissolved oxygen below 1 ppb within a flow rate range of 0 to 10 m/s. The Cr content in steel was changed from 0.02 to 2.4 wt%. Increasing the Cr content in the alloy, the FAC rate and oxide thickness decreased. The oxide porosity tends to decrease with the Cr content and immersion time owing to the development of Cr containing oxide. The oxidation behavior is not changed with the immersion time.

Opis:
In this paper, implementation of soft sensing technique for measurement of fluid flow rate is reported. The objective of the paper is to design an estimator to physically measure the flow in pipe by analysing the vibration on the walls of the pipe. Commonly used head type flow meter causes obstruction to the flow and measurement would depend on the placement of these sensors. In the proposed technique vibration sensor is bonded on the pipe of liquid flow. It is observed that vibration in the pipe varies with the control action of stem. Single axis accelerometer is used to acquire vibration signal from pipe, signal is passed from the sensor to the system for processing. Basic techniques like filtering, amplification, and Fourier transform are used to process the signal. The obtained transform is trained using neural network algorithm to estimate the fluid flow rate. Artificial neural network is designed using back propagation with artificial bee colony algorithm. Designed estimator after being incorporated in practical setup is subjected to test and the result obtained shows successful estimation of flow rate with the root mean square percentage error of 0.667.

Opis:
The development of photovoltaic (PV) panels has made solar-powered pumps a reality. The pump drivers are usually direct-current (DC) motors which are fed by power electronic converters with maximum power point tracking (MPPT) to extract the whole energy that the PV panels can generate depending on the environmental conditions including irradiation and temperature. The implementation of MPPT algorithm essentially involves sensing both an input current and an input voltage. Understandably, such realization is expensive. In this paper, a solar PV water pumping system based on DC to DC converter as MPPT module is considered. The system consists of a PV array, a DC to DC boost converter and the DC motor coupled to a centrifugal pump. A proposed method is employed to seek the maximum power point using the flow rate obtained from a single sensor. A comparison with conventional hill climbing technique is included in experimental results to prove feasibility of the proposed method.

A new method of indirect flow rate measurement in a pneumatic pipeline system was developed by the authors. The method enables to measure the controlled leakage in a branch line and was used to construct automatic measuring systems auditing the compressed air systems (CAS) piping. In the CAS audit the volume and cost of the leakage in a compressed air pipeline system is evaluated. Based on the authors’ patent, an automatic measuring system (AMS) for measurement of the leakage flow rate in industrial compressed air system piping, was developed. The AMS consists of a measurement device (MD) and a control system (CS). In the measurement device (MD) a novel bifunctional pneumatic proportional control valve is used. The AMS system will be used in the new research project “Mobile laboratory of compressed air system audit” based on the authors’ concept.

Opis:
The present analysis of the hole extension effect on the transpiration flow efficiency is a part of the research [1] which aims at defining a physical transpiration model of the flow through perforated plates. Perforated walls find a wide use as a method of flow control and effusive cooling. Some data on the L/D (hole length to diameter ratio) effect on the flow structure and mass flow rate may be found in the literature [2, 3], but all those works concern holes of a diameter at least one order of magnitude larger than those used in the simulations presented in this paper. Due to the size of the analyzed holes and their cylindrical shape, the only method of analysing the flow through such holes is the numerical method. In the conducted simulations, the holes were D = 0.6 mm, 0.3 mm and 0.125 mm in diameter and the perforation values were equal to 4%, 5%, 8% and 10%. The L/D ratio was changed between 0.25 and 8. The data bank of the flow through the cylindrical holes was produced. The hole extension has a significant influence on the obtained mass flow rate and, consequently, on the transpiration flow efficiency. In addition, entrance effects appear to be important.

Opis:
The Biopipe system is the first biological wastewater treatment system designed to remove carbonaceous and nitrogenous substances entirely within a pipe. The transformation mechanisms in the Biopipe system can be modelled using a physical model, and several experiments have been carried out to this study. The experimental work was carried out at the Al-Barakia wastewater treatment plant (BWWTP) in Iraq’s Najaf governorate that will be done to obtain continuous source of sanitary sewage flow and thus, maintain the pilot plant operation. Two tanks, two pumps, a Flow Control and Measuring Device, PVC Pipes, and an Aeration System make up the physical model. Seeding using activated sludge from a similar plant, The Biopipe system requires 28 days to get steady results and maximal COD, TN and TSS removal efficiency. The tests were carried out on a Biopipe system with recirculation with different value of influent flow rate and different recirculation ratio. The most important findings of the Biopipe system application indicated that system is better for removing COD than TN. When the recirculation ratio was equal to 9, the removal efficiency of chemical oxygen demand (COD) and total nitrogen (TN) achieved 66.50% respectively. The dissolved oxygen concentration rises to 5.75 mg/l when the recirculation flow rate is increased to 216 m3/day. In addition, it was found that the removal efficiency of biodegradable organics can be enhanced in case of low influent flow rate and high recirculation flow rate.

This paper presents analysis of results of investigations of flow rate of sand (Qs) and water (Qw) in an air lift pump. The investigations were performed on an air lift pump test rig, constructed in a laboratory on a scale of 1:1. The paper describes the construction and working principle of this air lift pump test rig and presents a methodology of derivation of empirical formulas for calculation of sand and water flow rate. A comparative analysis of the values of the sand and water flow rate obtained in direct measurements with analogical values of flow rate calculated with use of the derived empirical formulas was carried out. The research scope encompassed the derivation of the aforementioned empirical formulas in the PVC air lift pump with the internal diameter of the discharge pipe d = 0.03 m by the fixed sand-water mix delivery heads H: 0.40 m, 0.80 m, 1.20 m. To derive the empirical formulas for calculation of the sand and water flow rate, dimensional analysis and multiple regression was applied. In the air lift pump being tested, the water and sand flow rate felt along with the rise in the delivery head and the water flow rate was higher than the sand flow rate. Air pressure in such devices cannot be lower than 110 kPa and cannot exceed 150 kPa as for higher values of air pressure the sand and water flow rate starts to fall. The values of the sand and water flow rate calculated with use of the derived formulas coincide very well with the values determined from the direct measurements.
W artykule przedstawiono analizę wyników badań natężenia przepływu piasku (Qs) i wody (Qw) w podnośniku powietrznym. Badania wykonywano na wybudowanym w laboratorium w skali 1:1 stanowisku do badania podnośnika powietrznego. W artykule przedstawiono budowę i zasadę działania stanowiska badawczego oraz omówiono metodykę wyznaczenia empirycznych wzorów do obliczania natężenia przepływu piasku i wody. Przeprowadzono analizę porównawczą wartości natężenia przepływu piasku i wody wyznaczonych z bezpośrednich pomiarów z wartościami obliczonymi za pomocą wyznaczonych empirycznych wzorów. Zakres badań obejmował wyprowadzenie wzorów do obliczania natężenia przepływu piasku i wody w podnośniku powietrznym z tworzywa sztucznego PVC o średnicy wewnętrznej rurociągu tłocznego d = 0,03 m, przy zadanej wysokości podnoszenia mieszaniny piasku i wody H: 0,40 m, 0,80 m, 1,20 m. Do wyznaczenia empirycznych wzorów do obliczania natężenia przepływu piasku i wody zastosowano analizę wymiarową i metodę regresji wielokrotnej. W badanej konstrukcji podnośnika powietrznego wraz ze wzrostem wysokości podnoszenia mieszaniny piasku i wody, natężenie przepływu piasku i wody malało, a wartości natężenia przepływu wody były większe w stosunku do wartości natężenia przepływu piasku. W badanym urządzeniu ciśnienie powietrza nie może być mniejsze niż 110 kPa i nie powinno przekraczać 150 kPa, ponieważ przy wyższych ciśnieniach powietrza natężenie przepływu piasku i wody zaczynało spadać. Wartości natężenia przepływu piasku i wody obliczone za pomocą wyprowadzonych wzorów, bardzo dobrze pokrywały się z wartościami wyznaczonymi z bezpośrednich pomiarów.

The method for the selection of a calculation scheme for the evaluation of the flow behaviour of labyrinth seal with one straight fin, against smooth wall, was presented. Experimental results were obtained from measurement data carried out on the in house, vacuum test section. The advantage of the test rig is a circular shape of the labyrinth specimen, providing similar shape to configuration operated in practise. In computational fluid dynamics study different types of mesh resolution were tested, with variable volume discretization in the area of a labyrinth fin tip. Moreover, a wide range of turbulence models basing on k-ε and k-ω, exploiting the (Reynolds Average Navier Stokes) scheme, for the flow pattern evaluation, were examined. All obtained results were compared with literature data, covering research conducted on similar configurations. The presented study shows challenges as well as the possibilities of calculation simplification and compares results obtained by means of simulations and experiment. The proposed method is characterised by excellent agreement of computational results with experiment data.

Opis:
The objective of this study was to reduce the level of impurities in biogas to obtain a higher concentration of methane gas (CH4) in it. The biogas purification process was carried out in a packed scrubber using Monoethanolamine (MEA) compound as an absorbent. This research focused on the effect of the packing flow area and the optimum biogas flow rate for obtaining purified biogas with a high concentration of methane (CH4). The results of the study reveal that the packing flow area measuring 0.1963 cm2 is more optimal in the purification process compared to 1.7633 cm2 packing flow area. Different biogas flow rates at 0.3 L/min, 0.5 L/min, 1 L/min, and 12 L/min yield different results, and the highest concentration of CH4 at 90.141% is obtained from the slowest flow rate, which is 0.3 L/min. The slow flow rate and a small packing flow area equal to a longer contact time between MEA and the biogas flowing through it; hence, the absorption contact area is also greater compared to that with a faster flow rate; therefore, the highest level of CH4 is obtained at the slowest biogas flow rate.
