Opis:
W niniejszym artykule zostały zaprezentowane wyniki obliczeń numerycznych oddziaływania wiatru na przepływ powietrza w tunelach. Zagadnienie oddziaływania wiatru na przepływ powietrza w tunelach odgrywa istotną rolę przy projektowaniu wentylacji bytowej, systemów bezpieczeństwa pożarowego tuneli a w szczególności systemów wentylacji pożarowej oraz systemów detekcji pożaru. W przypadku nieuwzględnienia wiatru na etapie projektowania wyżej wymienionych systemów prawidłowe wykrycie pożaru oraz skuteczne funkcjonowanie systemu wentylacji pożarowej będą bardzo utrudnione, a w niektórych przypadkach nawet niemożliwe. Artykuł ten stanowi fragment prowadzonej przez autora pracy badawczej.
In this paper there are presented results of the numerical analyses of the wind influence on flow field in tunnels. The results show that wind shall be considered during ventilation design process.

Opis:
In line with current rapidly developing technology, mechanization in industry is increasing. In this case, all components that form a machine are becoming important. Compressor plays an important role in operations of numerous machineries. They are used for increasing pressure by compressing gas. Compressors have various types and especially in industries such as automotive, textile, and manufacturing, reciprocating compressors are frequently used. Reciprocating compressors consist of cylinder, piston, and crank and connecting rod mechanism. These components work by narrowing the volume inside the cylinder and increasing gas pressure inside. In this study, flow structure inside a reciprocating compressor was numerically analysed. For this purpose, models were created for 2 different crank angles of a reciprocating compressor. Simulations were made for different pipe angles of inlet pipe and outlet pipe. Valve openings were kept constant at 6 mm. Input and output angles of inlet and outlet pipes to cylinder was changed as 0°, 30°, 45°, 60° and 90°. As a result, it was determined that as the angle of inlet and outlet pipes changed, general flow structure inside the cylinder changed as well. Especially, there were differences in velocity vectors plotted for input and output of the flow from valve to cylinder.

Opis:
The work considers the modelling of flow in a complete mixed-flow pump with volute, including tip leakage flows, using both quasi-steady and true transient models of rotor/stator interaction. The CFX-TASCflow CFD package from AEA Technology is applied to calculate flows for a wide range of flow rates from about 0.2 to 1.4 Q/sub 0pt/. Fairly detailed flow structures have been predicted based on the flow rates, especially impeller inlet recirculation and separation on the suction side of the blades for suboptimal rates of flow, as well as strong secondary flows and separation in the volute for off-design conditions. The rotor/stator interaction influence on flow phenomena both in the impeller and volute have been investigated with very interesting results, providing good insight into the dynamics of flow close to the volute tongue. Based on the computational results, pump performance curves (Q-H, Q- eta /sub h/ and Q-P, eta /sub h/ being the hydraulic efficiency) have been obtained. The data from this numerical investigation have been used to improve the inlet part of the impeller blades, especially close to the tip. The geometry modifications have resulted in reduced cavitation in the impeller as well as noise at suboptimal rates of flow.

Opis:
This paper investigates the three-dimensional viscous ow in centrifugal impellers through theoretical analysis and numerical simulations, which is a summary of the authors' recent work. A quantitative evaluation of the dierent contributions to the streamwise vorticity is performed, namely, the passage vortices along the endwalls due to the ow turning; a passage vortex generated by the Coriolis forces proportional to the local loading and mainly active in the radial parts of the impeller; blade surface vortices due to the meridional curvature. In the numerical simulation the NASA Large Scale Centrifugal Compressor (LSCC) impeller with vaneless diuser is computed at three ow rates. An advanced Navier-Stokes solver, EURANUS/TURBO is applied with an algebraic turbulence model of Badwin-Lomax and a linear k-" model for closure, for dierent meshes. An in-depth validation has been performed based on the measured data. An excellent agreement is obtained for most of the data over a wide region of the ow passage. Structures of the 3D ow in the blade passage and the tip region, and their variations with ow rate as well, are analysed based on the numerical results.

Opis:
Sequential combustion was first applied to gas turbines more than 40 years ago, and almost half of these early machines are still operating. This form of oxidation leads to the flame-less combustion at a second chamber. In GT26, the second stage combustor has 24 SEV burners which are similar in action to the well known ABB EV burner. In this paper, a 3D numerical simulation of the first EV combustor and the second SEV-combustor are performed for normal operating conditions (exhaust mass flow 542 kg/s, exhaust temperature 610 C). Physical modelling of the flame-less oxidation is based on an original implementation of the Gri-Mech mechanism (325 chemical reactions) into the Fluent 5.4. Precise estimation of NOx emission and other pollutants has been done.

This paper presents the basic principles of construction of numerical models for 3D viscous turbulent flows through multi stage turbomachines. The great attention is given to such properties of the methods as accuracy, linear and non-linear stability, robustness and computational efficiency. It is shown that these properties can be guaranteed if the implicit Godunov’s type ENO scheme is used. A 3D code FLOWER has been developed within this concept. Using the code the numerical results are obtained for flows through high loaded compressor cascades, a turbine stage, a low-pressure multi stage turbine and a centrifugal compressor stage. The results of optimisation of a low-pressure turbine last stage are presented.

Opis:
From 2010 Warsaw University of Technology (WUT) and Institute of Aviation (IoA) jointly implement the project under the Innovative Economy Operational Programme entitled ‘Turbine engine with detonation combustion chamber’. The goal of the project is to replace the combustion chamber of turboshaft engine GTD-350 with an annular detonation chamber. During the project, the numerical group that aims to develop computer code allowing researchers to simulate investigated processes has been established. Simulations provide wide range of parameters that are hardly available from experimental results and enable better understanding of investigated processes. Simulations may be also considered as a cheap alternative for experiments, especially when testing geometrical optimizations. In this paper the analysis of simulation results of the combustion chamber of the Rotating Detonation Engine (RDE) investigated at the IoA in Warsaw is presented. Primarily, REFLOPS USG which has become a fundamental numerical tool in the research of the RDE at the IoA is briefly described and governing equations and numerical methods used are shortly presented. Some aspects of numerical simulations of the RDE, related to selection of combustion mechanism, and an initiation of rotating detonation are provided. Secondly, results of simulations of inviscid gas with numerical injectors of hydrogen are compared with available experimental results. Three different wave patterns are identified in numerical solution and briefly described. Results of simulations are compared to experimental results in combustion chamber. Results presented in this paper are part of the project UDA-POIG.01.03.01-14-071 ‘Turbine engine with detonation combustion chamber’ supported by EU and Ministry of Regional Development, Poland.

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.

The paper presents an analysis of the fluid flow in the cooling system of an internal combustion engine with oposite pistons. The purpose of the work was to optimize the flow of fluid through the channels located in the engine block. Simulation studies and subsequent iterations were performed using Ansys Fluent software. Two-equation k-epsilon turbulence model was used in the simulation model. Boundary and initial conditions were taken from previously made simulations conducted in AVL Boost software. The average wall temperature of the cylinder and the temperature of the outer walls of the cylinder were assumed for simulations. The results of the analyzes were graphically illustrated by the speed streamline distribution of velocity fields and temperature.

Opis:
Analizując dotychczasowe prace badawcze nad odpylaczami cyklonowymi z zastosowaniem modelowania numerycznego przepływów (Computational Fluid Dynamics – CFD) można stwierdzić, że stosowano głównie cztery modele numeryczne: k-ε, k-ε RNG, Reynolds Stress Model (RSM) oraz Large Eddy Simulations (LES). Celem niniejszej pracy była ocena dokładności i poziomu wiarygodności tych modeli na przykładzie cyklonu stosowanego w konstrukcjach cyklonowego wymiennika ciepła. Weryfikacji dokonano w zakresie wartości spadku ciśnienia i skuteczności odpylania mąki surowcowej. Otrzymane wyniki drogą obliczeniową porównano z wynikami pochodzącymi z rzeczywistej instalacji wypalania klinkieru. Uzyskane wyniki pozwoliły stwierdzić, że w przypadku cyklonów stosowanych w cyklonowych wymiennikach ciepła najbardziej dokładne okazały się modele RSM (w przypadku skuteczności odpylania) oraz LES (w zakresie spadku ciśnienia). Przeprowadzona analiza oraz wnioski mogą być pomocne w procesie definiowania strategii badań numerycznych, będących etapem optymalizacji konstrukcji cyklonów stosowanych w cyklonowych wymiennikach ciepła.
A review of studies on the cyclone separators using Computational Fluid Dynamics (CFD) that have been published so far indicates that research has primarily involved four numerical models: k-ε, k-ε RNG, Reynolds Stress Model (RSM) and Large Eddy Simulations (LES). The aim of this paper was to assess the precision and reliability of these models based on a cyclone used as part of cyclone suspension preheater. The assessment concerned the value of pressure drop and separation efficiency of the raw meal. Results obtained through computation were compared to those obtained in a real clinker burning installation. The obtained results showed that in the case of cyclone separators used in cyclone suspension preheater the RSM model (in the case of separation efficiency) and LES model (in the case of pressure drop) were most accurate. The performed analysis and its conclusions may prove useful for defining the strategy of numerical research aimed at optimizing the structure of cyclones used in cyclone suspension preheater.

Opis:
The disposal of ash in a thermal plant through the slurry pipe is subjected to some erosion wear due to the abrasive characteristics of the slurry. A simulation study of particle-liquid erosion of mild steel pipe wall based on CFD-FLUENT that considers the solid-liquid, solid-solid and solid-wall interaction is presented in this work.The multi-phase Euler-Lagrange model with standard k- ϵ turbulence modeling is adopted to predict the particulate erosion wear caused by the flow of bottom ash water suspension. Erosion rate for different particle size and concentration is evaluated at variable flow rate. It is observed that the pressure drop and erosion rate share direct relationships with flow velocity, particle size and concentration. The flow velocity is found to be the most influencing parameter. A model capable of predicting the erosion wear at variable operating conditions is presented.The simulation findings show good agreement with the published findings.

Opis:
The aim of this study was to investigate a possibility of using gaseous fuels of a low calorific value as a fuel for internal combustion engines. Such fuels can come from organic matter decomposition (biogas), oil production (flare gas) or gasification of materials containing carbon (syngas). The utilization of syngas in the barrel type Opposed-Piston (OP) engine arrangement is of particular interest for the authors. A robust design, high mechanical efficiency and relatively easy incorporation of Variable Compression Ratio (VCR) makes the OP engine an ideal candidate for running on a low calorific fuel of various composition. Furthermore, the possibility of online compression ratio adjustment allows for engine the operation in Controlled Auto-Ignition (CAI) mode for high efficiency and low emission. In order to investigate engine operation on low calorific gaseous fuel authors performed 3D CFD numerical simulations of scavenging and combustion processes in the 2-stroke barrel type Opposed-Piston engine with use of the AVL Fire solver. Firstly, engine operation on natural gas with ignition from diesel pilot was analysed as a reference. Then, combustion of syngas in two different modes was investigated – with ignition from diesel pilot and with Controlled Auto-Ignition. Final engine operating points were specified and corresponding emissions were calculated and compared. Results suggest that engine operation on syngas might be limited due to misfire of diesel pilot or excessive heat releas which might lead to knock. A solution proposed by authors for syngas is CAI combustion which can be controlled with application of VCR and with adjustment of air excess ratio. Based on preformed simulations it was shown that low calorific syngas can be used as a fuel for power generation in the Opposed-Piston engine which is currently under development at Warsaw University of Technology.

Opis:
Despite the fact that HCCI engines are distinguished by mixture homogeneity, some degree of stratification always appears inside a combustion chamber. It is especially applied to residual effect engines utilizing negative valve overlap. Mixture stratification is a result of the imperfect mixing of fresh air with trapped residuals. Direct fuel injection introduces stratification as well, due to fuel vaporization. As a consequence, the temperature within the combustion chamber is uneven. Thermal stratification affects auto-ignition timing and combustion evolution in a high extent. The purpose of this study was to evaluate a degree of thermal stratification in HCCI engine utilizing negative valve overlap. Investigations were performed using three-dimensional CFD model of the combustion system, made by using AVL FIRE software. Simulations were realized for various timings of fuel injection into the cylinder. It was found that fuel injection timing had a significant effect on the thermal stratification and resulting auto-ignition timing.

The article presents modeling of the work environment microclimate using numerical methods. The numerical models adopted for the calculations were based on an office located in the building of the Faculty of Civil Engineering of the Czestochowa University of Technology. Six computational variations were made that differed in the heating method, air supply and ventilation. The results of the numerical analysis for one of the models were compared with the test in the assumed measuring point recording temperature and relative humidity. The per-formed numerical analysis allows for a relatively quick assessment of the influence of the adopted boundary conditions on the formation of the microclimate in the work environment.
