• SIMILARITY SOLUTION FOR UNSTEADY BOUNDARY LAYER FLOW OF A MICROPOLAR NON- NEWTONIAN POWER LAW FLUID THROUGH A POROUS MEDIUM

Hiral Parmar*, M. G. Timol

Abstract


In the present paper, the two dimensional unsteady boundary layer flow of a micropolar non-Newtonian power law fluid near the rear stagnation point of a plane surface in a porous medium are studied. The similarity solutions are obtained using group theoretic technique. The application of two-parameter group reduce the number of independent variables by two and a set of auxiliary conditions from three to only one independent variable, and consequently the system of governing partial differential equations with boundary conditions reduces to a system of ordinary differential equations with appropriate boundary conditions.

Keywords


Similarity solution, micro-polar fluid, porous medium, Non-Newtonian.
