Variable viscosity and thermophoresis for Soret and Dufour's effects on MHD generation in a non‐Daracian porosity fluid

Abstract

The effect of thermophoresis on a magnetic field generation in a non-Daracian porous medium flow with the variation of the viscosity fluid in the presence of Soret and Dufour, thermal reaction and diffusion effects over a stretching surface is investigated in the present analysis. The governing equations of continuity, momentum, energy, and concentration are transformed into nonlinear ordinary differential equations, using similarity transformations and then solved numerically. The influence of various physical parameters on velocity, temperature, and concentration profiles are illustrated graphically, and the physical aspects are discussed in detail. Finally, the effects of related physical parameters on the skin friction, the rate of heat and mass transfer are also studied.
