Effect of Thermal Radiation on MHD Boundary Layer Flow of Nanofluid and Heat Transfer Over a Non-Linearly Stretching Sheet with Transpiration

In this paper the MHD boundary layer flow with heat transfer of nanofluid over a non-linear stretching sheet in presence of thermal radiation, magnetic field and suction/injection has been investigated numerically. The governing partial differential equations are reduced into ordinary differential equations by using similarity transformations. The transformed non-linear equations are solved by using finite difference scheme known as Keller Box method. The influence of Magnetic parameter (M), Thermal Radiation parameter (R), Brownian motion parameter (Nb), Thermophoresis parameter (Nt), Lewis number (Le), Prandtl number (Pr), suction parameter (S), non-linear stretching sheet parameter (n) on the velocity, temperature and nano-particle concentration profiles are shown graphically. The variation of the skin friction coefficient, Nusselt number and Sherwood numbers with variation in magnetic parameter, thermal radiation parameter, suction/injection parameter, Prandtl number and slip parameter are presented in tabular form. The results so obtained are compared with previously published results and they found in excellent agreement.
