Effects of Radiation and Chemical Reaction on MHD Unsteady Heat and Mass Transfer of Casson Fluid Flow Past a Vertical Plate

Effects of radiation and chemical reaction on MHD unsteady heat and mass transfer of Casson fluid flow past a vertical plate has been studied in this paper. The model equations are transformed into non-dimensional form by the as usual mathematical technique of transformation and the resultant non-dimensional partial differential equations are solved by using explicit finite difference method. The obtained results are plotted after stability test by using graphics software TECPLOT-9. The results are showed for various dimensionless parameters such as Casson parameter, Permeability of porous medium, Schmidt number, Grashof number, Prandtl number, Chemical reaction and Radiation parameter on velocity, temperature and concentration profiles along with the local skin friction, local Nusselt number and Sherwood number with the help of computer programming languages COMPAQ VISUAL FORTRAN 6.6a. The results are discussed with the help of graphs. Finally, we obtained that velocity decrease with an increase in Casson parameter, Permeability of porous medium and Chemical reaction while it increase with increasing values of Radiation parameter and Grashof number. Temperature increase due to Radiation parameter but decrease for Prandtl number. Therefore, the results of the present problem have an excellent agreement with the results of Raju et al. [2].
