Finite Element Analysis of Free Convection Heat Transfer Flow in a Vertical Conical Annular Porous Medium

摘要

In this paper, we study the heat transfer by Natural convection in a saturated porous medium including viscous dissipation in a vertical conical annular porous medium. Finite Element Method (FEM) has been used to solve the governing partial differential equations. Results are presented in terms of average Nusselt number, streamlines and isothermal lines for various values of Rayleigh number (Ra), Cone angle (CA), Radius ratio (Rr) and Viscous dissipation(ε).
