Abstract: | A kind simple postprocess procedure for classical Galerkin method for steady Navier-Stokes equations with stream function
form was presented in this paper. The main ideal was to construct an approximate interactive rule between lower frequency
components and higher frequency components by using the conception of Approximate Inertial Manifold (AIM) and a kind of new
decomposition of the true solution. It is demonstrated in this paper that this kind of postprocess Galerkin method could derive
a higher accuracy solution with lower computing efforts.
