A streamline diffusion nonconforming finite element method for the time-dependent linearized Navier-Stokes equations∗
Appl. Math. Mech. -Engl. Ed. 31 (7), 861-874 (2010)，-0001，（）：
A nonconforming finite element method of finite difference streamline diffusion type is proposed to solve the time-dependent linearized Navier-Stokes equations. The backward Euler scheme is used for time discretization. Crouzeix-Raviart nonconforming finite element approximation, namely, nonconforming (P1)2-P0 element, is used for the velocity and pressure fields with the streamline diffusion technique to cope with usual instabilities caused by the convection and time terms. Stability and error estimates are derived with suitable norms.
