Abstract

The paper deals with the effects of radiation and Soret number variation in the presence of heat source/sink on unsteady laminar boundary layer flow of a chemically reacting fluid along a semi-infinite vertical plate, taking the term Eckert number into account. A magnetic field of uniform strength is applied normal to the flow. The governing boundary layer equations are solved numerically, using Crank-Nicholson method and the simulation is carried out by coding in C-Programme. Graphical results for velocity, temperature and concentration fields and tabular values of Skin-friction, Nusselt and Sherwood numbers are presented and discussed at various parametric conditions. From this study, it is found that the Skin–friction, Nusselt number, temperature and velocity of the fluid increase in the presence heat source and for increasing values Eckert number (Ec).
