Highly Robust Boundary Condition for Incompressible Flow

Abstract

The method for posing boundary condition of pressure for incompressible flow on inlet and outlet boundary is presented. This method gives highly robust boundary condition since it is derived by imitating reality. Computational results show that the presented method can help computational algorithm to converge while the conventional method cannot. Discontinuity is still left in the steady-state result but not much enough to disturb all whole flow filed.
