ABSTRACT

The purpose of this paper is to find the admitted Lie group of the reduction of the Navier-Stokes equations

where

using the basic Lie symmetry method. This equation is constructed from the Navier-Stokes equations rising to a partially invariant solutions of the Navier-Stokes equations. Two-dimensional optimal system is determined for symmetry algebras obtained through classification of their subalgebras. Some invariant solutions are also found.
