摘要：

A numerical study of heat transfer and entropy generation of a magneto-hydrodynamic (MHD) nanofluid flow inside an enclosure filled with a fluid saturated porous medium is presented. The flow is influenced by time periodic discrete heat sources along the short side walls. A detailed physical insights of time dependent flow and heat transfer is presented based on various flow governing parameters such as Grashof number (10(4)-10(6)), Hartmann number (1-50), Darcy number (0.001-1.0) and nanoparticle volume fraction (0.0-0.20) with a fixed Prandtl number (6.2). The resulting energy flux vectors are simulated to analyze the convection generated heat transfer ratio. Entropy generation and Bejan number are used to study the performance of the system.
