Heat and Mass Transfer of Laminar Boundary Layer Flow of Non-Newtonian Power Law Fluid past a Porous Flat Plate with Soret and Dufour effects

This article numerically studies the heat and mass transfer of a laminar boundary layer flow of a non-Newtonian power law fluid past a porous flat plate. The solution takes the suction/injection, power law index, Soret and Dufour effects into consideration. The governing boundary layer partial differential equations along with boundary conditions are first cast into a dimensionless form by a similarity transformation and the resulting ordinary differential equations are then solved numerically using implicit finite difference scheme. The influence of Soret and Dufour parameters, suction/injection, power law index, Prandtl number and Lewis number on non-dimensional velocity, temperature and concentration fields are discussed graphically. Tha variation of Power law index, Soret and Dufour numbers on heat and mass transfer rates is presented in tabular form.
