NUMERICAL ANALYSIS OF THE NAVIER-STOKES EQUATIONS IN CONVECTIVE FORM WITH DIRICHLET BOUNDARY CONDITIONS IN THE DOMAIN WITH AN INCOMING ANGLE

The article considers the flow of a Newtonian fluid modeled using the incompressible Navier-Stokes equation in a non-convex polygon with Dirichlet boundary conditions. Discretization using FEM with weight is made. A series of numerical tests was carried out. A set of optimal parameters of the method has been determined, for which an advantage over classical approaches is achieved.
