AN APPROXIMATE SOLUTION OF BOUNDARY VALUE PROBLEM IN CONVECTION PROBLEM WITH CHEMICAL REACTION

In this work, we firstly use the application of Finite Difference Method (FDM) and Homotopy Perturbation Method (HPM) to find the approximate solution of Two-Point boundary Value Problem (BVPS) which appear in the fully developed mixed convection with chemical reaction. HPM is a simple method to control the convergent solution using He polynomial which is optimally determined. The result shows the effectiveness and realibility of FDM than HPM for this convection problem.
