Краткое описание

In this paper effect of heated side wall partially and inclination on natural convection flow in a cavity has been analyzed with Lattice Boltzmann Method (LBM) using Cu/water nanofluid. The middle place of partial cooled wall varied from y = L/4 to 3L/4 whereas place of high temperature side wall is fixed at center. Study has been conducted for different Rayleigh numbers (Ra) 103 to 105 and volume fraction changes between 0 and 15 % while inclined angle grow from 0° to 60° with interval 30°. This research was compared against past studies and showed a good agreement. The comparisons show that the average Nusselt number increases with growth of Rayleigh number and volume fraction for all of the states. The effect of nanoparticles augments by increment of inclination angles at each case and the best case for heat transfer observed middle-middle case so middle-bottom case is the weakest at this property.
