FE Approximation of the Vorticity-Stream function Equations for Incompressible 2-D flows

비압축성 2-D 유동에 대한 와도-흐름함수 방정식의 유한요소 근사

The object of this paper is the treatment of how to make the vorticity boundary condition instead of pressure in the primitive variable case. An improved algorithm for solving the vorticity-stream function equation is presented. The linear finite element approximation for the solution of Wavier-Stokes and Stokes flows is constructed. Not only regular domain but also complicate domain can be analyze d, using this formulation.
