MOMENTUM AND HEAT TRANSMISSION IN UNSTEADY BOUNDARY LAYER FLOW OF A ROTATING NON-NEWTONIAN FLUID WITH TINE DEPENDENT SUCTION

摘要

This paper deals with momentum and heat transmission in unsteady boundary layer flow of rotating non-Newtonian fluid with time dependent suction, when the plate velocity is constant. Constitutive equations of momentum and energy are formulated. These equations are non-dimensionalised and solved with the permissible boundary conditions. Velocity and temperature profiles are drawn varying the fluid parameters. The numerical values of shearing stresses are entered in the tables for different values of fluid parameters. It is noticed that the non-Newtonian parameter and the suction parameter influence the flow field to a great extent and the prandtl number affects the temperature field.
