Abstract
The effects of chemical reaction, radiation absorption, diffusion thermo on MHD free convective flow of a nanofluid bounded by porous medium past a semi-infinite flat plate are analyzed. The plate is moved with a constant velocity, temperature and the concentration are assumed to be fluctuating with time harmonically from a constant mean at the plate. The solutions of the governing equations are evaluated by using the perturbation technique. We have considered the nano-fluids namely Cu-water and TiO2-water nanofluids. The effects of governing flow parameters on velocity, temperature and concentration are discussed through graphs. For engineering interest, we evaluated the skin friction, Nusselt number and Sherwood number and computationally discussed.
