Quasi linearization of mixed convection micropolar flow near stagnation point with suction

Abstract

This paper presents a numerical solution for the mixed convection flow of an incompressible micropolar fluid near a stagnation point on a horizontal cylinder, with suction effects. The governing partial differential equations have been solved by using the quasi-linearization technique and the results have been compared with those obtained by using the finite difference method. Profiles for the velocity, microrotation and temperature functions are presented for a wide range of the buoyancy and the suction parameter values. It is noticed that micropolar fluids help in the reduction of drag forces and also act as a cooling agent, whereas suction enables us to control the boundary layer flow.
