On the use of Green’s formula for solution of the Navier-Stokes equation

Abstract

A general iterative procedure for solving Navier-Stokes system in stream function-vorticity variables  is considered. Using the fundamental solution for Laplace operator we find a boundary condition for vorticity. We define an application such that the vorticity is its fixed point. In order to construct this application we solve a Dirichlet problem for Laplace equation and a boundary value problem for vorticity equation in divergence form. A FEM and a classical BEM are used to accomplish this task. Some numerical experiments are carried out.
