摘要
In this article we study the stability for all positive time of the Crank-Nicolson scheme for the two-dimensional Navier-Stokes equations. More precisely, we consider the Crank-Nicolson time discretization together with a general spatial discretization, and with the aid of the discrete Gronwall lemma and of the discrete uniform Gronwall lemma we prove that the numerical scheme is stable, provided a CFL-type condition is satisfied.
