Analysis of viscosity variation with MHD on circular stepped plates in couple stress fluid

Abstract

The viscosity variation on circular stepped plates with MHD in Couple Stress fluid is analyzed. The modified Reynolds equation applicable to couple stress fluid is obtained by considering Viscosity Variation along with the film thickness. The expressions are obtained for dimensionless Pressure, Work load and time. The outcomes indicate that the viscosity variation reduces the pressure and squeeze film time. But, the Magnetic effect with couple stress fluid increases the Work load.
