Abstract
A numerical study of thermal diffusion effect on a mixed convective heat and mass transfer transient flow along a stretching sheet with constant heat and mass fluxes is completed under the action of a uniform magnetic field. A mathematical model related to the problem is developed from the basis of studying magnetohydrodynamics (MHD). Some dimensionless quantities have been used to transform the model to a non-dimensional system of equations. Study of chief physical interest of the flow as shear stress, Nusselt number and Sherwood number are also noted here. The system of momentum, energy and concentration equation is solved numerically by an explicit procedure of the finite difference technique. The stability criteria and convergence conditions are obtained for this problem. The collected numerical values of flow variables are illustrated in graphs for different values of associated parameters. The physical aspects of the problem are discussed in detail from the graphical representation. Last of all, some important findings of the present problem are concluded in this work.
