Natural Convection and Entropy Generation of Nanofluids in a Square Cavity

Abstract: The present paper investigates the natural convection and entropy generation of nanofluids in a square cavity. The left and right vertical walls of the cavity are maintained at a local high temperature TH (heat source) and a local cold temperature TC, respectively. The horizontal walls are adiabatic. The governing equations are discretised by using the finite volume method. A computer program based on the SIMPLER algorithm is developed and compared with the numerical results found in the literature. Results ar… Show more

“…They concluded that an increment in the nonNewtonian parameters, reduces the fluid friction in the region close to the pipe wall. Natural convection and entropy generation of nano-fluids in a square cavity was concluded by Bouchoucha and Bessaih [10]. Unsteady heat and mass transfer effects on an impulsively started infinite vertical plate in the presence of porous medium was studied by Loganathan et al [11].…”

“…Bejan [27] developed a model for estimating and minimizing the irreversibility due to heat transfer configurations. Bouchoucha and Bessaih [28] conducted a numerical investigation of natural convection heat transfer and entropy generation in a square cavity filled with nanofluid. They showed the average Nusselt number increases with volume fraction of nanoparticles and Rayleigh number.…”
