A Comparative Study of Thermal Radiation Effects on MHD Flow of Nanofluids and Heat Transfer Over a Stretching Sheet

Abstract

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.

“…Mixed convective flow of Cu-water nanofluid with chemical reaction, thermal radiation and heat source/sink has been explored by Mahanthes et al [9] using Laplace transform method. Sravan Kumar and Rushi Kumar [10] studied the impact of thermal radiation on natural convective MHD flow of nanofluids and heat transfer over a stretching sheet. Loganathan et al [11] analyzed the influence of radiation effect on an unsteady natural convective flow of Cu, Al 2 O 3 , TiO 2 , and Ag water based nanofluids past an infinite vertical plate.…”
