Abstract

ABSTRACT The natural convection of the nanofluids from a vertical accelerated plate in the presence of the radiation flux and magnetic field is observed in this study. Initially, the plate with a temperature higher than the temperature of nanofluids is at rest and then it accelerates moving upward and then the wall temperature decreases. The governing unstedy equations are solved by the explicit method based on the forward finite difference. Three different types of water-based nanofluids containing copper Cu, aluminium oxide Al2O3 and titanium dioxide TiO2 are taken into consideration. The hydrodynamics and thermal performance of the nanofluids is calculated. The results of the computation show that the velocity profiles are influenced by the type of the nanofluids, Grashof number, radiation parameter, magnetic field and volume fraction of nanoparticles. The shear stress profiles of the nanoflids Cu-water has the lowest value. The temperature distributions are very slightly different for the same volume fraction for all nanofluids. The heat tansfer from plate to the nanofluids is influenced by radiation parameter, volume fraction and prandtl number. This study in model of the cooling system in engineering applications.
