A finite element scheme for incompressible viscous flow calculations
Abstract
A finite element scheme for two-dimensional incompressible viscous flows in primitive variables is proposed. An upwind factor finite element method is devised to solve the momentum equations, and the continuity equation is satisfied by the correction of the pressure field. Numerical experiments are carried out for a driven cavity and a diffuser. The Reynolds number for the cavity flow is 100.0, and for the diffuser is 50,000.0. The numerical result of the scheme for the cavity flow is compared with that by another numerical method and satisfactory agreement is found.
