Numerical Analysis on Natural Convection Inside a Square Enclosure having Porous Partition

Theoretical analysis has been conducted on the performance of buoyancy motivated heat and fluid movement within a square inclusion having porous partition occupied with air. For investigating the flow behaviour inside the inclusion, numerous pertinent parameters such as stream function, isotherm, Nusselt number (Nu) along the conducting wall have been determined while varying partition width (from 0.1 to 0.3) and Darcy number (from 10-3 to 10-1 ). Ansys, fluent software is used to determine the solution of governing differential equations. The significant finding of the work that heat allocation rate enhances with Da and reduces with partition width.
