The transient free convection magnetohydrodynamic motion of a nanofluid over a vertical surface under the influence of radiation and heat generation

Abstract

The main purpose of this article is to study the effect of MHD, internal heat generation, thermal radiation and nanoparticle volume mass on an unsteady free convection motion of a nanofluid over the infinite vertical sheet. Nanofluids involving nanoparticles of silver, aluminum oxide, copper and titanium oxide with a nanoparticle volume concentration range smaller than or equal to 0.04 were taken. The numerical solutions of governing boundary value problems were gained by the Laplace transform algorithm and symbolic computation software MATLAB. The effects of MHD, heat generation, radiation and nanoparticle volume concentration on the velocity, energy and mass descriptions are depicted graphically. The skin friction coefficient, Nusselt number and Sherwood number are also investigated.
