Heat transfer in an MHD flow of an Erying-Powell fluid over a convectively heated stretching sheet in the presence of heat source and thermal radiation

Abstract

This study investigates the effects of viscous dissipation, Joule heating, and a heat source on the magnetohydrodynamic flow of an Eyring-Powell fluid over a convectively heated stretched sheet with convective boundary conditions. The fluid flows over a surface heated by a hot fluid from beneath through convection. The fluid's viscosity follows a Reynolds model, while its thermal conductivity varies linearly with temperature. By applying the standard similarity method, the governing nonlinear partial differential equations are transformed into ordinary differential equations. These equations are then solved numerically using the Spectral Quasi-Linearization Method (SQLM). The study presents and discusses graphical results that highlight the key fluid variables influencing velocity and temperature profiles. The findings of this research could have significant implications for various engineering applications, such as heat exchanges, chemical reactors, and thermal management systems.
