Abstract

The effects of radiation absorption, first order chemical reaction and diffusion thermo on MHD free convective heat and mass transfer flow of a nanofluid past a semi infinite vertical flat plate are analyzed. The temperature and concentration at the surface are assumed to be oscillatory type. Four types of cubic nano particles which are uniform and size namely, Silver (Ag), Aluminum (Al₂O₃), Copper (Cu) and Titanium Oxide (TiO₂) with water as a base fluid is taken into account. The set of ordinary differential equations are solved by using regular perturbation technique. The impact of various flow parameters on nanofluid velocity, temperature, concentration as well as the friction factor coefficient, the rate of heat and mass transfer coefficients are derived and discussed through graphs and tables.
