Flow Control of Non-Newtonain Fluid using Riga Plate: Reiner-Phillipoff and Powell-Eyring Viscosity Models

Abstract

This article investigates the controlling effects of electromagnetic field generated by Riga plate on the boundary layer flow of non-Newtonian fluid. Two classical viscosity models of non-Newtonian fluids namely; Powell-Eyring and Reiner-Phillipoff fluid models have been considered to study the different behaviors of non-Newtonian fluid flow. Numerical solution of the problem in the presence of strong suction is obtained using the nonlinear shooting method. The results are studied in terms of modified Hartmann number, non-Newtonian fluid parameters and the Bingham number. Linear regression is performed on the numerical results to present the correlation expression for the skin friction.
