Effects of Radiation and Magnetic field on the flow and heat transfer of a nanofluid in a rotating frame

Abstract

We analysed the flow and heat transfer characteristics of a nanofluid in porous medium bounded by a moving vertical semi-infinite permeable flat plate in presence of   constant heat generation/absorption, radiation and chemical reaction in a rotating frame. The slip velocity is assumed to oscillate in time with constant frequency so that the solutions of the boundary layer are the same as oscillatory type. The dimensionless governing equations for this investigation are solved analytically using perturbation approximation. In this study two types of nanofluids, namely -water and -ethylene glycol are used and the heat transfer characteristics are analysed for different shapes of nano particles. The effect of various parameters on the flow and heat and mass transfer characteristics are discussed through graphs.
