Higher Order Wall Boundary Conditions for Incompressible Flow Simulations

Abstract

In this paper, the new higher order wall boundary conditions are proposed for solving the incompressible flows. The square driven cavity flows are simulated by using the variable order method of lines with the present wall boundary conditions. The variable order method of lines is constructed by the spatial discretization, i.e., the variable order proper convective scheme for convective terms and the modified differential quadrature method for diffusive terms, and time integration. The 2nd, 4th, 6th, and 8th order solutions are presented and these results show this higher order boundary conditions are very promising for the incompressible flow simulations.
