Study of MHD Boundary Layer Flow Over a Stretching Surface in Porous Media

Abstract

This research paper investigates the magnetohydrodynamic (MHD) boundary layer flow over a stretching surface in porous media. The study aims to analyze the effects of various parameters, such as the magnetic field, porosity, and stretching rate, on the flow characteristics and heat transfer. The governing partial differential equations are transformed into a system of nonlinear ordinary differential equations using similarity transformations. The resulting equations are then solved numerically using the Runge-Kutta-Fehlberg method. The effects of the governing parameters on the velocity and temperature profiles, as well as the skin friction coefficient and local Nusselt number, are presented graphically and discussed in detail. The results indicate that the magnetic field and porosity have significant influences on the flow and heat transfer characteristics. The findings of this study have potential applications in various fields, including materials processing, geothermal engineering, and heat exchanger design.
