A new efficient relaxation scheme in conjunction with a multigrid method is developed for the Euler equations. The LU SSOR scheme is based on a central difference scheme and does not need flux splitting for Newton iteration. Application to transonic flow shows that the new method surpasses the performance of the LU implicit scheme.
An accurate shock capturing scheme is developed for high speed flow. The flux limited dissipation scheme can be converted to a symmetric TVD scheme in the case of a scalar conservation law. Application to an oblique shock wave problem shows the improved resolution and accuracy when compared to the results obtained by the adaptive dissipation method, while exhibiting comparable computational efficiency.
