Abstract:

The paper presents the results of computing aerodynamic properties of the CRTF2A counter-rotating cowled fan developed as part of the European VITAL program. To achieve these results, we used the following software packages: NUMECA FINE TURBO, ANSYS CFX and CIAMs own 3D--IMP--MULTI hydrocode. We use the RANS approach to model turbulent flows. We performed a three-dimensional computation, completing Reynolds-averaged Navier --- Stokes equations by various turbulence models for the following relative angular frequency modes: n = 1 and 0.9. We used the following turbulence models available in the software packages: k--ε (ANSYS CFX, 3D--IMP--MULTI), k--ε (ANSYS CFX, NUMECA FINE TURBO, 3D--IMP--MULTI), SST (NUMECA FINE TURBO, ANSYS CFX, 3D--IMP--MULTI). We plotted head characteristics for each software package and determined the main differences. We plotted adiabatic efficiency and total pressure ratios as functions of height for the first and second rotors at the maximum efficiency points for both modes in the ANSYS CFX, NUMECA FINE TURBO and 3D--IMP--MULTI software packages

Abstract:

Abstract In the present study, CFD calculations are presented for the three types of water-based nanofluids Al2O3/water, CuO/water and TiO2/water with 0.1% volume fraction. These calculations are done with ANSYS-CFX and as geometry the SRBTL test loop as scaled down test loop for a VVER-1000 reactor core design is used. The goal of this study is to evaluate the CFD program against the SRBTL test loop core as a scaled core for applying water-based nanofluids as coolant. ANSYS-CFX simulation data are validated against the RELAP5/MOD3.2 simulation data for pure water. This comparison shows a good agreement. The simulation results for the nanofluids and water including Re number, temperature, viscosity, pressure drop and heat transfer coefficient through the SRBTL test loop core are compared. The results of the comparisons show that the SRBTL test loop core is suitable to extract experimental data of water-based nanofluids for using them as coolant in the VVER-1000 reactor.

Abstract:

Abstract Numerical mathematical models of non-contact oil free scroll, Roots and screw vacuum pumps are developed. Modelling was carried out with the help of software CFD ANSYS-CFX and program TwinMesh for dynamic meshing. Pumping characteristics of non-contact pumps in viscous flow with the help of SST-turbulence model were calculated for varying rotors profiles, clearances, and rotating speeds. Comparison with experimental data verified adequacy of developed CFD models.

Abstract:

This paper presents the results of numerical investigation of the flow in a vaneless diffuser of centrifugal compressor stage. Simulations were performed using both a commercial CFD package ANSYS CFX and the own-designed computer program. Steady conditions involving SST turbulence model were used for the calculations using CFX. To consider the interaction between impeller and diffuser, not just a diffuser but the whole stage was calculated. The own-designed methodology is based on solving of conservation equations with assumptions that flow in a diffuser is steady state and axisymmetric. The flow area is divided into the flow core and boundary layers. Results of calculation were compared with experimental data.

Abstract:

A numerical study is conducted by using ANSYS CFX 14.5, a commercial computational fluid dynamics program to predict the thermal performance of a counter and parallel flow on triangular double layered microchannel heat sink for various channel aspect ratios. Findings reveal that the counter flow configuration leads to a better heat transfer performance for low channel aspect ratio (α < 4) and higher Reynolds Number (Re > 700). For the parallel flow configuration, improved performance is normally shown when channel aspect ratio, α is more than 4 and lower Reynolds Number (Re < 700).
