Optimal design with entropy generation minimization approach in combined natural convection with surface radiation in a two‐dimensional enclosure

Abstract: Analysis of combined natural convection with surface radiation in a two-dimensional enclosure is carried out. To search the optimal location of the heat source, the entropy generation minimization approach and conventional heat transfer parameters are used and compared. Air is considered as an incompressible fluid and transparent media filling the enclosure with a steady and laminar regime. The enclosure internal surfaces are also gray, opaque, and diffused. The governing equations are solved using the finite … Show more

“…27,28 Analysis of combined natural convection and entropy generation with surface radiation in a square cavity was studied and reported that enhancement of radiation emissivity reduces entropy generation. 29 Several investigations on buoyant transport and entropy production of infinite porous and nonporous geometries filled with a variety of nanofluids have been performed by considering effects, such as magnetic field and nonuniform thermal profiles. Shahi et al 30 numerically studied entropy production in a cavity filled with Cu-H 2 O nanofluid containing protruded heater and found an optimum source location for maximum heat dissipation with minimum irreversibility.…”
