Abstract:

This paper provides an error analysis for the Crank–Nicolson extrapolation scheme of time discretization applied to the spatially discrete stabilized finite element approximation of the two-dimensional time-dependent Navier–Stokes problem, where the finite element space pair $(X_h,M_h)$ for the approximation $(u_h^n,p_h^n)$ of the velocity $u$ and the pressure $p$ is constructed by the low-order finite element: the $Q_1-P_0$ quadrilateral element or the $P_1-P_0$ triangle element with mesh size $h$. Error estimates of the numerical solution $(u_h^n,p_h^n)$ to the exact solution $(u(t_n),p(t_n))$ with $t_n\in (0,T]$ are derived.
