Abstract

An analysis has been carried out to study the mixed convection flow, heat and mass transfer of an incompressible electrically conducting Maxwell fluid past a vertical stretching sheet in the presence of chemical reaction with thermal diffusion (Soret) and diffusion-thermo (Dufour) effects. The governing nonlinear partial differential equations along with the appropriate boundary conditions are non-dimensionalized using suitable similarity variables. The resulting transformed ordinary differential equations are then solved numerically by shooting technique with fourth order Runge - Kutta method. The influence of various physical parameters on the flow, heat and mass transfer characteristics are discussed through graphs and tables. The results are physically interpreted. A comparison with the previously published results has been carried out and the results are found to be in good agreement. The conclusion is drawn that the flow field, rate of heat and mass transfer coefficients are significantly influenced by Dufour, Soret and Eckert numbers.
