EFFECTSOFTHERMALRADIATIONAND PRESSURE WORK ON MAGNETO MARANGONI FLUID FLOW OVER A CIRCULAR SURFACE

Abstract

After taking into account the pressure work and the surface tension, a computer study has been 
conducted on a thermally radiative and magnetic Marangoni boundary layer on a heated circular 
surface. The present work numerical model consists of a collection of ordinary differential equations 
that express several physical parameters, which were generated from the governing partial 
differential equations with appropriate boundary conditions. The buoyancy parameter increases 
velocity magnitudes, whereas the magnetic parameter and the ratio of surface tension have the 
opposite effects, according to the numerical analysis of the effective variables. As the magnetic 
influence rose, so did the temperature magnitudes. The Marangoniration number, Prandtl number, 
and buoyancy parameter were shown to increase the Nusselt number.
