Abstract
Heat Transfer analysis in a square porous annulus is conducted with respect to heating of 4 inner walls along with outer horizontal walls and cooling of outer vertical walls cooling. Darcy law along with Boussinesq approximation is applicable. Two phases of porous medium such as solid and fluid phase are in thermal equilibrium. The governing equations are approximated using Galerkin method and converted into algebraic equation using finite element method. The fluid is found to flow in vertical cells along left and right half of duct. The top section of duct is found to have minimum thermal energy as compared to other parts of duct.
