Free Convection Heat Transfer and Entropy Generation in an Odd-Shaped Cavity Filled with a Cu-Al2O3 Hybrid Nanofluid

The present paper aims to analyze the thermal convective heat transport and generated irreversibility of water-Cu-Al2O3 hybrid nanosuspension in an odd-shaped cavity. side walls are adiabatic, internal external borders enclosure isothermally kept at high low temperatures Thand Tc, respectively. control equations based on conservation laws formulated dimensionless form worked out employing Galerkin finite element technique. outcomes demonstrated using streamlines, isothermal lines, heatlines, isolines Bejan number, as well rate entropy Nusselt number. Impacts Rayleigh nanoparticles concentration (?hnf), volume fraction Cu ?hnf ratio (?r), width (WR) have been surveyed discussed. results show that, for all magnitudes numbers, increasing intensifies generation. Moreover, WR enhances transport.
