Abstract
Thermal analysis of simultaneous natural convection and radiation in moving porous fin is conducted. Homotopy analysis method (HAM) is applied to solve energy equation considering two types of boundary conditions. The accuracy of HAM is validated through comparison with the numerical results. The effects of embedding parameters on the dimensionless temperature and heat transfer rate are studied. The results show that the fin temperature reaches quickly to the surrounding temperature for two types of fins when the value of porous parameter increases. It is observed that the temperature along the length of fin decreases for both infinite and finite fins when the values of C T and Rd increase. Further, a slowdown in the heat transfer rate at the fin tip is found with the increased value of Peclet number.
