Properties of difference schemes for solving twodimensional NavierStokes equations associated with boundary conditions prescribed on a solid surface
Abstract
Different methods of implementing boundary conditions on a solid surface in the numerical solution of twodimensional NavierStokes equations are examined. In particular, attention is given to an approach whereby the system equations are solved separately. In this case, with twodimensional NavierStokes equations for an incompressible viscous fluid written in velocitypressure, velocityvortex, and vortexcurrent function variables, the method of boundary condition implementation is shown to be algorithmically universal and can be based on a twoparameter formula proposed previously for the approximation of wall vorticity.
