Thermal and Mass Stratification Effects on MHD Flow Past an Accelerated Vertical Plate with Variable Temperature and Exponential Mass Diffusion Embedded in a Porous Medium

Abstract

This study looks at how the impacts of thermal and mass stratification on magnetohydrodynamic (MHD) flow alongside a vertically accelerating plate featuring variable temperature and exponential mass diffusion within a porous medium. The Laplace transform technique is utilized to solve the governing equations related to flow, energy, and mass diffusion. Subsequently, the impact of stratification on the flow field, temperature, and mass diffusion is examined. The study indicates that thermal and mass stratification significantly affects the profiles of velocity, temperature, and mass diffusion. Additionally, it has been discovered that a stable state for the velocity is achieved as both stratification parameters are raised, whereas stable states for the temperature and concentration occur when mass stratification is heightened but thermal stratification is reduced.
