流控制

Under the unstaggered grids, the continuous equation is replaced with the elliptic different one of the pressure, which is derived by the finite-analytic method, and a modilfied new SIMPLER algorithm is proposed to be used as an equal-order pressure-velocity coupling scheme. A simple procedure is applied to determine the cell-face velocity independent of the under-relaxation factor used in solving the momentum equations.
