Thermal radiation and heat transfer effects of magneto hydrodynamic flow of nanofluid over a rotating frame

The flow and heat characteristics of a nanofluid in a non-porous medium bounded by a moving vertical semi-infinite permeable flat plate has been discussed taking into account the presence of constant heat generation, absorption, radiation and chemical reaction in a rotating frame. The slip velocity was assumed to oscillate in time with constant frequency. So the solutions of the boundary layer were the same as that of the oscillatory type. The dimensionless governing equations were solved analytically. Two types of nanofluids (Cu-water and Cu-ethylene glycol) were used in this study and the heat transfer characteristics were analysed for different shapes of nano particles. The effect of various parameters on the flow and heat and mass transfer characteristics have been discussed through graphs. The velocity and temperature profiles of the fluid were more influenced by radiation and magnetic field parameters. Suction parameter and chemical reaction parameter helped to reduce the velocity of the fluid and the effect of these parameters were high on Cu-EG nano fluid. Shape of the nano particles have not shown any significant difference in velocity and temperature profiles of the fluid. Decrease in the nano particle shape enhanced the velocity profiles of the fluid. Increase in the rotation caused a decrease in the velocity profiles of the fluid
