Powolny przepływ cieczy lepkiej w płaskim kanale o nagłym lokalnym rozszerzeniu

In this paper the numerical solution of viscous fluid flow with low Reynolds number in the channel with a locally recessed walls is described. The method of finite differences is used to solve the Navier-Stokes equations in the Helmholtz from for two-dimensionat flow. The flow through channels with different dimensions of local enlargement is considered. The results of numerical investigations for Reynolds number are shown in graphs of the streamlines and lines of constant vorticity.
