MAGNUM MARANGONI FLUID FLOW ACROSS A CIRCULAR SURFACE: THE ROLE OF THERMAL RADIATION AND PRESSURE

Abstract

Taking into account the pressure work and surface tension, computational work has been carried out on a magneto Marangoni boundary layer that is thermally radiative on a heated circular surface. A system of ordinary differential equations describing various physical characteristics constitutes the numerical model of the present investigation, which was evolved from the governing partial differential equations with appropriate boundary conditions. Increasing the buoyancy parameter raises the magnitudes of the velocities, according to the numerical study of the effective variables, but the magnetic parameter and the ratio of the surface tension had the reverse impact. As the magnetic effect was amplified, the temperature magnitudes rose. The results showed that the Nusselt number is improved by the Marangoni ratio number, the Prandtl number, and the buoyancy parameter.
