A COMPARATIVE STUDY OF THERMAL RADIATION EFFECTS ON MHD FLOW OF NANOFLUIDS AND HEAT TRANSFER OVER A STRETCHING SHEET

In this work, the steady natural convective boundary layer flow of nanofluid and heat transfer over a stretching sheet in the presence of a uniform transverse magnetic field is investigated. We consider two different base fluids and three different nanoparticles were examined as nanofluid. A new model was used in the simulation of nanofluid. Similarity transformations are used to obtain a system of nonlinear ordinary differential equations. The resulting equations are solved numerically by shooting method with Runge-Kutta fourth order scheme (MATLAB package). The effects of various parameters describing the transport in the presence of thermal radiation, buoyancy parameter, magnetic parameter and heat source/sink and nanoparticle volume concentration on the nanofluid velocity, temperature, the heat transfer coefficient and skin-friction coefficient are studied through graphs and table. Furthermore, comparisons with published results are in very good agreement.
