High-Reynolds Number Solutions of Incompressible Navier-Stokes Equations using Vectorial Operator Splitting
The steady incompressible Navier-Stokes equations in primitive variables are solved by implicit vectorial operator-splitting. The method allows for complete coupling of the boundary conditions. Conservative approximations for the advective terms are employed on irregular staggered grids. The technique is used here for solving two benchmark problems. Numerical solutions for the flow in a lid-driven rectangular cavity with aspect ratio two (up to Re = 6000) and for the flow over backward-facing step in a channel (up to Re = 1400) on appropriate grids are presented.
