### SEMI-ANALYTICAL METHOD FOR SOLVING NON-LINEAR EQUATION ARISING OF NATURAL CONVECTION POROUS FIN

**ABSTRACT**

In the present study, the problem of non-linear model arising in heat transfer through the porous fin in a natural convection environment is presented and the homotopy perturbation method is employed to obtain an approximate solution, which admits a remarkable accuracy.
