A block-line-Gauss-Seidel (LGS) method is developed for solving the incompressible and compressible Navier-Stokes equations in two dimensions. The method requires only one block-tridiagonal solution process per iteration and is consequently faster per step than the linearized block-alternating-direction-implicit (ADI) methods. Results are presented for both incompressible and compressible separated flows: in all cases the proposed block- LGS method is more efficient than the block-ADI methods. Furthermore, for high-Reynolds-number weakly separated incompressible flow in a channel, which proved to be an impossible task for a block-ADI method, solutions have been obtained very efficiently using the new scheme.
