Annals of Unsteady Solutions of Thermal Boundary Layer Equations by using Finite Difference Method

Abstract. We studied the equation of continuity and derived the Navier-Stockes (N-S) equations of motion for viscous compressible and incompressible fluid flow, Boundary layer and thermal boundary layer equations are then derived. Then we studied unsteady solutions of thermal boundary layer equations. Thermal Boundary layer equations have been non-dimensionalised by using non-dimensional variable and the equations have been derived from Navier-Stokes equation and concentration equation by boundary layer technique. The non-dimensional boundary layer equations are non-linear partial differential equations. These equations are solved by using finite difference method. The solution of heat and mass transfer flow is studied to examine the velocity, temperature and concentration distribution. The effect on the velocity, temperature and concentration profiles for various parameters entering into the problems are separately discussed and shown graphically
