ABSTRACT

The current analysis is devoted to observing the influence of Soret and Dufour effects on MHD stagnation point flow along a vertical stretching sheet. Effects of variable viscosity and thermal conductivity are also considered in our study. The governing equations of flow are transformed into ordinary differential equations using similarity transformations and which are solved numerically by using Runge-Kutta fourth order scheme with shooting technique. The significant properties and effects of various physical parameters such as viscosity variation parameter, thermal conductivity variation parameter, Soret number, Dufour number, Hartmann number on velocity, temperature and species concentration distributions are presented through graphs.

Key words: Soret and Dufour effects, variable viscosity, variable thermal conductivity, shooting technique.
