TL;DR: In this article, the homotopy perturbation method (HPM) has been applied to solve a nonlinear heat transfer problem, where the heat transfer coefficient and specific heat coefficient were assumed to be dependent on temperature.
Abstract: Homotopy Perturbation Method (HPM) has been applied to solve a nonlinear heat transfer problem. Natural convection around an isothermal horizontal cylinder was studied. Heat transfer coefficient and specific heat coefficient were assumed to be dependent on temperature. Outcomes were compared with solution of heat transfer equation with constant properties. Solutions of HPM were compared with numerical results for different cases, and variation of Nusselt number was obtained and investigated.
