Book Description
A numerical technique has been developed to obtain a solution for steady, transonic blade element flow in an axial compressor rotor of a turbomachine. Radius variation and stream surface convergence are included. The mixed-out exit conditions include shock wave losses and viscous mixing losses. The time-dependent Navier-Stokes equations in conservation law form are cast in a relative coordinate system suitable for describing rotor blade element flow. A discretized method of characteristics is used to determine the boundary conditions along the blade surface and exit plane. Steady, supersonic, uniform flow conditions are specified at upstream infinity, and periodicity is enforced on the remaining free boundaries. The hyperbolic/parabolic system of equations describing the mixed flow problem are approximated by the explicit MacCormack finite-difference scheme. The time-dependent numerical solution rapidly converges to a steady-state result. Comparisons are made with experimental data for two-dimensional cascade flows and rotor blade element flow. (Author).

Book Description
A computer program to analyze steady-state transonic flow in turbomachinery components has been developed. The time-dependent partial differential system of equations is approximated by the MacCormack finite-difference algorithm. The program is operational for two-dimensional compressor cascades or quasi-three-dimensional rotors including radius and stream surface thickness variations. A hybrid method of characteristics is used to impose the boundary constraints upon the flow field. Flow field periodicity is used at the free surface boundaries. Output consist of a flow field description and mixed-out properties of the flow at the exit. (Author).

Computational Fluid Dynamics Review 1998 (In 2 Volumes)
Author: Mohamed M Hafez
Publisher: World Scientific
ISBN: 9814495778
Category : Science
Languages : en
Pages : 1169
Book Description
The first volume of CFD Review was published in 1995. The purpose of this new publication is to present comprehensive surveys and review articles which provide up-to-date information about recent progress in computational fluid dynamics, on a regular basis. Because of the multidisciplinary nature of CFD, it is difficult to cope with all the important developments in related areas. There are at least ten regular international conferences dealing with different aspects of CFD.It is a real challenge to keep up with all these activities and to be aware of essential and fundamental contributions in these areas. It is hoped that CFD Review will help in this regard by covering the state-of-the-art in this field.The present book contains sixty-two articles written by authors from the US, Europe, Japan and China, covering the main aspects of CFD. There are five sections: general topics, numerical methods, flow physics, interdisciplinary applications, parallel computation and flow visualization. The section on numerical methods includes grids, schemes and solvers, while that on flow physics includes incompressible and compressible flows, hypersonics and gas kinetics as well as transition and turbulence. This book should be useful to all researchers in this fast-developing field.
