Studying the Impact of Some Thermal Properties in MHD Fluids on Heat and Mass Transport Flow Within a Plate Embedded with Radiation and Heat Source

Abstract

This research investigates the impact of certain thermo-physical properties of a fluid on the flow of heat and mass transfer through free convection. The fluid in consideration is a chemically reacting, viscous, incompressible, and electrically conducting substance flowing past an infinite porous plate. The process is influenced by a uniform transverse magnetic field, with the fluid being optically thin, allowing the modeling of thermal radiative heat loss through the Rosseland approximation. A uniform magnetic field is applied perpendicularly to the plate and the fluid experiences a normal suction velocity, while the heat flux at the plate remains constant. The study involves solving the dimensionless partial differential equations governing the phenomenon through analytical methods, specifically employing the Olayiwola Generalized Polynomial Approximation Method (OGPAM). The obtained results illustrate the influence of various thermo-physical parameters on fluid flow, as well as heat and mass transfer characteristics, presented graphically. Skin-friction coefficient and Nusselt number values at the plate are numerically derived and discussed for different physical parameter values, presented in tables. The research also explores the effects of a generating heat source on fluid velocity and temperature, revealing that an increase in thermal radiation amplifies both the velocity and temperature profiles of the flow, thereby intensifying the convective flow.
