convection heat and mass transfer in a hydromagnetic flow of a second grade fluid in the presence of thermal radiation and thermal diffusion

the convection heat and mass transfer in a hydromagnetic flow of a second grade fluid past a semi-infinite stretching sheet in the presence of thermal radiation and thermal diffusion are considered. the governing coupled non-linear partial differential equations describing the flow problem are transformed into non-linear ordinary differential equations by method of similarity transformation. the resulting similarity equations are solved numerically using runge–kutta shooting method. the results are presented as velocity, temperature and concentration fields for different values of parameters entering into the problem. the skin friction, rate of heat transfer and mass transfer are presented numerically in tabular form. in addition, the results obtained showed that these parameters have significant influence on the flow, heat and mass transfer.
