In this paper, the magnetohydrodynamic effects on heat transfer and thermal radiation at a stagnation point flowing in a nanofluid containing different types of nanoparticles namely, copper (Cu ), alumina ( Al2o3 ) and titania (Tio2 ) through a porous medium have been investigated
numerically. By using appropriate transformation for velocity and temperature into a set of nonlinear coupled ordinary differential equations which are solved numerically. Numerical results are presented for velocity and temperature profiles for different parameters of the problem as magnetic field parameter, porous medium parameter, nanoparticle volume fraction parameter, thermal radiation parameter, nanoparticle parameter and the ratio of the gradient of velocities parameter , etc. Also the effects of the pertinent parameters on the skin friction and the heat fluxes are obtained and discussed numerically and illustrated graphically.
