EFFECTS OF THERMAL RADIATION AND PRESSURE WORK ON MAGNETO MARANGONI FLUID FLOW OVER A CIRCULAR SURFACE

Abstract

A computational work has been performed on a thermally radiative and magneto Marangoni boundary layer on a heated circular surface upon considering the pressure work and the surface tension. As developed from the governing partial differential equations with proper boundary conditions, the current work numerical model comprises a set of ordinary differential equations which pronounce multiple physical parameters. The numerical analysis of the effective variables revealed that increasing the buoyancy parameter increases the velocity magnitudes while opposite effects were found for the magnetic parameter and the ratio of the surface tension. The temperature magnitudes increased upon increasing the magnetic effect. It was indicated that the Marangoni ratio number, Prandtl number and the buoyancy parameter enhance Nusselt number.
