Abstract:

Several kind of new numerical schemes for the stationary Navier-Stokes equa-
tions based on the virtue of Inertial Manifold and Approximate Inertial Manifold, which
we call them inertial algorithms in this paper, together with their error estimations are pre-
sented. All these algorithms are constructed under an uniform frame, that is to construct
some kind of new projections for the Sobolev space in which the true solution is sought.
It is shown that the proposed inertial algorithms can greatly improve the convergence rate
of the standard Galerkin approximate solution with lower computing effort. And some
numerical examples are also given to verify results of this paper.

Key words: Navier-Stokes equations, error estimation, inertial algorithms
