Abstract

Very recently, there has been an affordable amount of work carried out by scientists/researchers, on radiative heat transfer in nanofluids due to their abundant applications. Particularly, the conception of radiative heat transfer is extremely employed in nanofluid Solar Collectors. Driven by these, the present work is worries with Radiative heat transfer of Nanofluids. Steady, two dimensional, nonlinear hydromagnetic stratified physical phenomenon flow of viscous, incompressible nanofluid over a nonlinearly stretching surface with thermal radiation, in the presence of variable heat generation and viscous dissipation along with variable temperature is investigated for two sorts of nanofluids is created by intermixture solid spherical nanoparticles with water such as Cu-Water nanofluid and Ag-Water nanofluid. Governing equations of the problem are nonlinear partial differential equations which are reduced to nonlinear ordinary differential equations by means of similarity transformations. The resultant equations are then solved numerically exploitation best Nachtsheim- Swigert shooting iteration scheme for satisfaction of asymptotic boundary conditions along with fourth order Runge-Kutta Integration technique. The effects of the magnetic interaction parameter, heat source/sink parameter, viscous dissipation parameter, radiation parameter, Prandtl number, solid volume fraction parameter and nonlinear stretching parameter on flow and heat transfer characteristics are analyzed. As a verification of the numerical scheme adopted, the numerical results of the problem is compared with that of previously published work in the absence of nanoparticles, magnetic field, heat source/sink and radiation and found be in are in splendid agreement. Also the numerical values of skin friction at wall and the nondimensional rate of heat transfer are conferred in tabular form.
