The incompressible navier-stokes equations are exactly recovered from this incompressible lbgk model numerical simulations of the plane poiseuille flow, the unsteady 2 - d shear decaying flow, the driven cavity flow, and the flow around a circular cylinder are performed. Finally, orthogonal polynomials as the partial solutions of obtained helmholtz equations were used for derivation of analytical solution of incompressible uid equations in 1d, 2d and 3d space for rectangular boundary. There exist many solution strategies for the incompressible navier-stokes equations one of the oldest is the splitting method proposed by chorin (1968) and temam (1969), often refered to as chorin's method.

Leray in [5] showed that the navier-stokes equations (1), (2), (3) in three space dimensions always have a weak solution (p,u) with suitable growth properties uniqueness of weak solutions of the navier-stokes equation is not known. Abstract- in this paper, we present analytical solutions of two dimensional incompressible navier-stokes equations (2d nses) for a time dependent exponentially decreasing pressure gradient term using orlowski and sobczyk transformation (ost) and cole-hopf transformation (cht).
