ResumoA three-dimensional numerical method based on the lower-upper symmetric-Gauss-Seidel implicit scheme in conjunction with the flux-limited dissipation model is developed for solving the compressible Navier-Stokes equations. A new computer code based on this method requires only 9 μs per grid point per iteration on a single processor of a Cray YMP computer and executes at the sustained rate of 175 MFLOPS. A reduction of three orders of magnitude in the residual for a high-Reynolds-number flow using 636K grid points is obtained in 38 min
