Non-Linear Thermal Radiation and Slip Effect on Boundary Layer Flow and Heat Transfer of Suspended Nanoparticles Over a Stretching Sheet Embedded in Porous Medium with Convective Boundary Conditions

An analysis is carried out to study the convective heat transfer of steady two-dimensional slip flow of nanofluid immersed in a porous medium over a stretching sheet in the presence of nonlinear thermal radiation in its own plane. The similarity equations are solved numerically using Runge-Kutta-Fehlberg fourth-fifth order method with Shooting method. The velocity and temperature profiles are presented graphically for different values of flow pertinent parameters. The skin friction coefficient and Nusselt number are discussed for three types of nanoparticles, namely Aluminum Oxide, Copper and Titanium Oxide. Effects of the solid nanoparticle volume fraction, permeability parameter, thermal radiation parameter and temperature ratio parameter on the fluid flow and heat transfer characteristics are thoroughly examined. It is observed that Temperature gradient at the surface increases for higher nanoparticle volume fraction, radiation parameter and Biot number.
