Opis:
W pracy przedstawione zostały zależności zmian przepuszczalności złoża czasie wypłukiwania z niego substancji wysokolepkich za pomocą czynnika myjącego dla różnych rodzajów mediów oraz przy różnym początkowym nasyceniu złoża olejem. Zaproponowano zależność pozwalającą przewidzieć ciśnienie na wlocie do złoża na podstawie prędkości wypływu cieczy. W związku z tym możliwe było opisanie procesu elucji ze złoża substancji oleistych o dowolnych lepkościach, niezależnie od stopnia wymycia ich ze złoża.
A dependence of permeability changes of a bed during the washout of high- viscosity substances using water as washing out agent for various types of media and at different initial oil saturation of the bed is presented in the paper. A universal relationship allowing one to predict pressure at the reservoir inlet on basis of liquid flow velocity is proposed. Therefore, it is possible to describe the elution of oily substances with different viscosities from the bed, regardless their washout degree.

Przedmiotem pracy było badanie przebiegu procesu wymywania zaolejonych złóż za pomocą roztworów surfaktantów pod wpływem działania sił grawitacyjnych. Na podstawie przeprowadzonych prac określono, iż całkowity czas procesów przemywania cieczy wzrasta wraz ze stężeniem roztworów surfaktantów i ich napięciem powierzchniowym. Rezydualne nasycenie złoża olejem wzrasta wraz ze stężeniem surfaktantu w roztworze przemywającym. Nasycenie końcowe olejem proporcjonalnie wzrasta wraz ze wzrostem napięcia powierzchniowego roztworów przemywających.
The paper deals with processes of gravitational elution of oil from porous media using solutions of surfactants. It was found that the total time of oil displacement increased with the increase of concentration of surfactants and their surface tension. Residual content of oil in the porous bed also increased with higher concentration of surface active agents and with higher values of surface tension.

Opis:
The combat potential of future warships will be directly related to the use of modern electronic devices being parts of advanced systems, such as, for instance, radar systems, fire aiming systems, fire detection systems, electric drive systems, and even electronic and radio-electronic weaponry, railguns and lasers, installed on these warships. The capacity and functionality of these devices is continually increasing, at decreasing mass and dimensions, which results in higher power consumption. Heat collection becomes a growing problem in operation of these devices. The paper presents a concept of the use of the CPL (Capillary Pumped Loop) cycle for passive heat collection from precise electronic devices used on warships. It also includes the description of the experimental rig and discussion of the results of laboratory tests performed on this rig and confirmed using the mathematical model developed by the authors.

Opis:
Cavitation is a multiphase phenomenon including vapor bubbles creation and collapse occurring alternately at high frequency in liquid stream. Creation of bubbles is possible under low pressure conditions, which occur for example during acceleration of the liquid. The collapses of bubbles generate pressure waves which spread through the flow. Working under cavitation condition is especially dangerous for power machines such as pumps and turbines, because it can lead to serious damage of blades. To investigate cavitating flow over a foil a test rig was built. The test rig included chamber with the blade fixed to the disc that enabled to set different angles of attack. The flow rate of water was changed by means of pump’s motor variable frequency drive. As the flow rate was increased, the velocity in chamber rose and pressure dropped. This led to cavitation structures appearance and development on the suction side of the blade. For different flow conditions the pictures of cavitating flow were taken and examined. Moreover, the pressure and the inlet and outlet of the chamber were recorded, as well as the value of volumetric flow rate. That enabled to determine the cavitation number, a parameter that describes intensity of cavitation in the flow, for each case.

Opis:
Every change in the bottle geometry as well as every change of physical and rheological properties posesa risk of excessive gas entrainment during a filling process. To maintain satisfactory filling efficiencythere is a need to optimise this process with respect to all adverse phenomena which affect the fluidflow, such as spluttering on the bottom, air caverns formation and air entrainment with incoming liquid.This paper comprises numerical simulations of two filling methods. The first method involves dosingwith a pipe placed over the free liquid surface of a fully filled bottle. The second method covers fillingwith a pipe located near the bottom. Moreover, the influence of rheological properties and surfacetension values is considered. The comprehensive analysis of amount of entrained air represented byair volume fraction in dispensed liquid let the authors define the influence of filling speed on themechanism and amount of entrapped air.

Opis:
The article presents the results of a computational fluid dynamics (CFD) analysis of gas-liquid multiphase flow. The simulation was conducted using CFD code and the Euler–Euler approach. The presented study relates to the non–reactive, steady-state, turbulent flow of water and carbon dioxide mixture in a 3D pipe. Separation phenomenon between phases is observed. The solution was obtained using a mixture model. Different values of carbon dioxide volume fraction were taken into account in the analysis of the results. The analysed cases were compared thanks to the obtained calculations results. The main purpose of the simulations was to show streamlines, velocity, pressure, and volume fraction distribution that could be useful in developing pipeline systems in many industrial applications, especially for CO2 separators.

Opis:
Multiphase flow meters are used to measure the water-liquid ratio (WLR) and void fraction in a multiphase fluid stream pipeline. In the present study, a system of multiphase flow measurement has been designed by application of three thallium-doped sodium iodide scintillators and a radioactive source of 133Ba simulated by Monte Carlo N-particle (MCNP) transport code. In order to capture radiations passing across the pipe, two direct detectors have been installed on opposite sides of the radioactive source. Another detector has been placed perpendicular to the transmission beam emitted from the 133Ba source to receive radiations scattered from the fluid flow. Simulation was done by the MCNP code for different volumetric fractions of water, oil, and gas phases for two types of flow regimes, namely, homogeneous and annular; training and validation data have been provided for the artificial neural network (ANN) to develop a computation model for pattern recognition. Depending on applications of the neural system, several structures of ANNs are used in the current paper to model the flow measurement relations, while the detector outputs are considered as the input parameters of the neural networks. The first, second, and third structures benefit from two, three, and five multilayer perceptron neural networks, respectively. Increasing the number of ANNs makes the system more complicated and decreases the available data; however, it increases the accuracy of estimation of WLR and gas void fraction. According to the results, the maximum relative difference was observed in the scattering detector. It was clear that transmission detectors would demonstrate the difference between the flow regimes as well. It is necessary to note that the error calculated by the MCNP simulator is <0.5% for the direct detectors (TR1 and TR2). Due to the difference between the data of the two flow regimes and the errors of data in the simulation codes of the MCNP, it was possible to separate these flow regimes. The effect of changing WLR on the efficiency for a constant void fraction confi rms a considerable variance in the results of annular and homogeneous flow s occurring in the scattering detector. There is a similar trend for the void fraction; hence, one can easily distinguish changes in efficiency due to the WLR. Analysis of the simulation results revealed that in the proposed structure of the multiphase flow meter and the computation model used for simulation, the two flow regimes are simply distinguishable.

Opis:
Flotation process involves aggregation of the particles based on the material/compound type of random mixtures such as ores and seawater. It is primarily used in pretreatment of water desalination and other industrial applications. The process makes use of various fluid mechanics principles as multifluids are involved. The multi-fluids in most of the flotation processes are of different phases, such as air and water. Like any other process, the efficiency of flotation is important, and hence most of the studies have been dedicated to understanding how the various parameters are affecting the flotation process. Among various parameters, fluids properties and flow parameters chiefly affect the flotation process. In particular, the bubble-particle interaction of the flotation process has been of interest as it is one of the cost-effective ways to enhance flotation efficiency. In this review, the authors present the latest developments in such parametric studies. This paper could be of interest to research students, academic researchers, and practitioners who want to contribute to (or take from) flotation research.

Opis:
Deep bed filtration is an effective method of submicron and micron particle removal from the fluid stream. There is an extensive body of literature regarding particle deposition in filters, often using the classical continuum approach. However, the approach is not convenient for studying the influence of particle deposition on filter performance (filtration efficiency, pressure drop) when non-steady state boundary conditions have to be introduced. For the purposes of this work the lattice-Boltzmann model describes fluid dynamics, while the solid particle motion is modeled by the Brownian dynamics. For aggregates the effect of their structure on displacement is taken into account. The possibility of particles rebound from the surface of collector or reentrainment of deposits to fluid stream is calculated by energy balanced oscillatory model derived from adhesion theory. The results show the evolution of filtration efficiency and pressure drop of filters with different internal structure described by the size of pores. The size of resuspended aggregates and volume distribution of deposits in filter were also analyzed. The model enables prediction of dynamic filter behavior. It can be a very useful tool for designing filter structures which optimize maximum lifetime with the acceptable values of filtration efficiency and pressure drop.

Opis:
The majority of publications and monographs present investigations which concern exclusively two-phase flows and particulary dispersed flows. However, in the chemical and petrochemical industries as well as in refineries or bioengineering, besides the apparatuses of two-phase flows there is an extremely broad region of three-phase systems, where the third phase constitutes the catalyst in form of solid particles (Duduković et al., 2002; Martinez et al., 1999) in either fixed bed or slurry reactors. Therefore, the goal of this study is to develop macroscopic, averaged balances of mass, momentum and energy for systems with three-phase flow. Local instantaneous conservation equations are derived, which constitute the basis of the method applied, and are averaged by means of Euler’s volumetric averaging procedure. In order to obtain the final balance equations which define the averaged variables of the system, the weighted averaging connected with Reynolds decomposition is used. The derived conservation equations of the trickle-bed reactor (mass, momentum and energy balance) and especially the interphase effects appearing in these equations are discussed in detail.

Opis:
Emulsions are interesting dispersed systems that are necessary for a number of technological processes. Their flow through porous structures have many applications in the field of chemical engineering. Enhanced Oil Recovery (EOR) techniques, soil remediation and various treatment methods of oily wastewater are good examples of emulsion flow in porous structure. The phenomenon of dispersed system flow through porous media is not easy to describe, mainly because of rheological behavior of emulsions and porous structure properties. During two phase flow of oil and water through porous bed it is possible to observe the interception of oil to porous structure, as well as filtration of oil in pores. In this study, we tried to examine the influence of the fraction size as well as migration process history on permeability of porous bed.

Opis:
Gamma-ray tomography experiments have been carried out to detect spatial patterns in the porosity, in a 0.27 m diameter packed steel column using a first generation computed tomography (CT) system. The CT scanner consists of a NaI(Tl) detector 5.08 cm in diameter, and an encapsulated 137Cs (3.7 GBq) radioactive source, located opposite to the center of the detector. The detector and the source, mounted on a fixed support and the column, can rotated and dislocate by two stepping motors controlled through a microprocessor. Different sizes of stainless steel Raschig rings (12.6, 37.9 and 76 mm) have been examined. The primary objective of this work is to detect spatial patterns and statistical information on porosity variation in packed distillation columns. Horizontal scans, at different vertical positions of the packed bed were made for each size of Raschig rings. Radial porosity variation within the packed bed has been determined. This study has demonstrated that the porosity and its spatial distribution in a metallic packed column can be measured with adequate spatial resolution using the gamma-ray tomography technique. After validation of this first generation CT, the turntable design to rotate and dislocate the 60Co or 137Cs sealed gamma-ray sources and multidetector array for the third generation industrial computed tomography was also developed.
