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.
Keywords: Non-newtonian fluid, suction/injection, power law index, Soret and Dufour number, finite difference method
