Influence of Mass Transfer and Chemical Reaction on MHD Flow Through a Porous Medium Past an Exponentially Accelerated Vertical Plate With Thermal Stratification and Radiation
An investigation of transient magnetohydrodynamics (MHD) flow, heat, and mass transfer through an exponentially accelerated vertical plate through a porous environment under the influence of a heat source and radiation has been conducted. The uniqueness of the current study is that it examines the effects of different parameters under the influence of thermal stratification. The fundamental equations have been solved using the Laplace transformation technique to accurately represent the flow problem. The results of the flow problems are studied for both the cases with and without stratification to understand the problem clearly. The steady state is attained quickly in the presence of stratification, in comparison to that without stratification. The effects of permeability of the porous medium and the magnetic field are examined. The novelty of this study is the analysis of the flow of MHD through a porous medium in the presence of radiation, thermal stratification, and chemical reaction through an exponentially accelerated vertical plate. This study may be motivated by the need to improve our knowledge of fluid flow in a variety of engineering and environmental contexts where these kinds of conditions are common, such as thermal management, geothermal energy extraction, and chemical processing industries.
