Abstract
Numerical solutions of three-dimensional unsteady compressible viscous flows for several cases have been obtained using two time-marching pr ocedures: a noniterative alternating direction implicit (ADI) scheme a nd a generalized minimal residual (GMRES) method using an iterative ve rsion of the ADI scheme as a preconditioner. Results obtained are comp ared with each other and also with experimental data. It is found that the GMRES scheme can reduce CPU time by as much as 60% compared to th e noniterative ADI scheme.
