Abstract A numerical study of natural convection in a square cavity subjected to the thermals boundary conditions on the sidewalls is presented and discussed. The fluid is Newtonian and equations governing the flow field and the heat transfer are given in dimensionless form. The finite volume method was adopted to solve the algebraic system. Influence of the Prandtl and the Rayleigh numbers on heat transfer and the flow field is illustrated and discussed as the stream functions, isotherms, horizontal velocity, local and average Nusselt numbers. Results indicate that improved heat transfer is more pronounced with increasing More >

Abstract Fresh water available on earth is very scared. Yet the demand of fresh water is incessantly increasing, due to population growth and rapid industrialization. According to the United Nations, in 2025, 63% of the world’s population will be living in scarce water areas. The provision of freshwater is becoming a gradually more important issue in many areas of the world. Oceans are the only available source for large amount of water. Ocean water presents high salinity, so there is a need to desalinate ocean water for everyday consumption. Solar stills are widely used in solar… More >

Abstract A finite volume code used for detailed analysis of forced-convection flow in a horizontal channel containing eight heat sources simulating electronic components. The study deals the effect of variations of Reynolds number, the volume fraction and the good choice of type of nanoparticles added to the base fluid. The study shows that the rate of heat transfer increases with increasing Reynolds number and the volume fraction of nanofluids but not infinitely. The analysis of the dynamic and thermal field shows that the heat transfer is improved, with the increase in the Reynolds number and the More >
