Entropy Generation of Nanofluid in a Porous Cavity by Lattice Boltzmann Method

Abstract

This investigation compared with other numerical studies and found to be in excellent agreement. The results depict the maximum total entropy generation due to the fluid friction and temperature gradient is generated in the vicinity of a high-temperature wall. Also, the results indicate that the average Nusselt number and entropy generation are an increasing function of the Rayleigh number, porosity, and Darcy number, but the entropy generation is a decreasing function of the volume fractions of the nanofluid.
