Navier—stokes computations of hypersonic flows

R. Hillier, D. Kirk, S. Soltani

The current interest in hypersonic flows is leading to significanteffort both to develop CFD methods and also to provide experimentaldata for their evaluation. In our research we…

An evaluation of iterative methods in the solution of a convection—diffusion problem

Y.T. Feng, G.J. Huang, D. R. J. Owen, D. Perić

In this paper we investigate the performance of CGS, BCGSTAB and GMRES with ILU preconditioner for solving convection‐diffusion problems. Numerical experiments indicate that…

Integral transform method for boundary layer equations in simultaneous heat and fluid flow problems

H.A. Machado, R.M. Cotta

The two‐dimensional steady boundary layer equations, forsimultaneous heat and fluid flow within ducts, are handled through thegeneralized integral transform technique. The…

Preconditioned cg‐like methods for solving non‐linear convection—diffusion equations

Gh. Juncu, I. Iliuta

The paper presents the numerical performance of the preconditionedgeneralized conjugate gradient (PGCG) methods in solvingnon‐linear convection — diffusion equations…

The efficient solution of fluid dynamics problems by the combination technique

Michael Griebel, Veronika Thurner

We study the sparse grid combination technique as an efficient methodfor the solution of fluid dynamics problems. The combination technique needsonlyO(h^–1_n(log(h^–1_n))^d–1)grid…

Numerical study of non‐equilibrium processes in high enthalpy flows

E. Schall, Y. Burtschell, D. Zeitoun

Non‐equilibrium hypersonic viscous flows with high enthalpyconditions have been computed with an implicit time‐dependentfinite‐difference scheme. This scheme accounts for both…
