• COMBINED EFFECTS OF VARIABLE MAGNETIC FIELD AND POROUS MEDIUM ON THE FLOW OF MHD FLUID DUE TO EXPONENTIALLY SHRINKING SHEET

Abstract

The present paper investigates the effects of variable magnetic field and porous media on the flow of viscous fluids over an exponentially shrinking sheet. The boundary layer approximation and similarity transformation in exponential form are used to transform the governing partial differential equations into coupled nonlinear ordinary differential equations. The power series method is utilized to obtain the closed form solution of the governing equations. The results obtained have been presented through graphs and tables, and discussed. The analysis reveals that the flow and heat transfer can be controlled significantly by controlling the suction parameter, magnetic field and porous medium permeability.
