Transient Convection Fluid Flow with Heat and Mass Flux in a Fixed Vertical Plate with Radiation
نویسندگان
چکیده
The investigation of the transient convection fluid flow with heat and mass flux in a fixed vertical plate with radiation is presented. The dimensionless governing equations were solved using the Laplace transform method to obtained the analytical expressions of velocity, temperature and concentration profiles of the fluid. Skin friction, Nusselt number and Sherwood number are computed respectively. The effects of various parameters associated with flow like Prandtl number Pr, Schmidt number, modified Grashof number N, Radiation parameter F, chemical reaction parameter K, and time t are studied with the help of graphs and tables. It is observed that the temperature increase with increasing Pr, N and t while concentration increase with increasing K and decrease with increasing Sc and t but the velocity always increase with increasing Sc, N and t.
