Unsteady MHD Free Convective Chemically Absorption Fluid Past an Impulsively Accelerated Plate with Thermal Radiation
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2014, Vol 2, Issue 12
Abstract
A theoretical study on free convective heat and mass transfer flow of an electrically conducting incompressible viscous fluid past an impulsively accelerated permeable plate embedded in Darcian (thermal) absorption media in presence of thermal radiation and first order chemical reaction is presented in this paper. The governing equation of motions are first non-dimensionalised and then transformed into a set of ordinary differential equations by employing a suitable periodic transformations. The closed form of expression for velocity, temperature and concentration fields as well as skin- friction, Nusselt and Sherwood numbers are obtained in terms of various physical parameters present. It is observed that, the radiation absorption parameter increases the temperature as well velocity, but decelerates the heat transfer rate. It is also observed that, the chemical reaction parameter enhances both the heat as well as mass transfer rates.
