• Abstract

In this paper, a new finite element scheme for Navier-Stokes equations is proposed, in which three different partitions( in the two dimensional case) are used to construct finite element subspaces fo the velocity field and the pressure. The error estimate of the finite approximation is given. The precision of this new scheme has the same order as the scheme $Q_2/P_0$, but it is more economical that the scheme $Q_2/P_0$.
