HEAT AND MASS TRANSFER EFFECTS ON PARABOLIC FLOW PAST AN ACCELERATED ISOTHERMAL VERTICAL PLATE IN THE PRESENCE OF CHEMICAL REACTION AND HALL CURRENT

Abstract

The investigation focuses on the unstable parabolic flow of an electrically driven fluid past an impermeable, unbounded, isothermal, perpendicular plate in the presence of a first-order chemical reaction and Hall current. The Laplace method, which transforms time-domain differential equations into frequency-domain differential equations, is used to solve the governing equations. We have covered the graphical interpretation of concentration, velocity, and temperature profiles for several physical criteria such as the Prandtl number, the thermal Grashof number, the mass Grashof number, the Schmidt number, the Hartmann number, and the skin friction. The accuracy of estimating the velocity increase resulting from a chemical reaction is improved by taking into account Grashof numbers (Gr and Gc), Hall current (h), and their interactions. It is also clear that the velocity decreases as the Hartmann, Schmidt, and Prandtl numbers increase. These findings are crucial for understanding the dynamics of fluid flow and chemical reactions in various industrial processes, such as metallurgy, electroplating, and material processing. They can also inform the design of more efficient and effective systems for these applications. Received: April 15, 2023Revised: June 7, 2023Accepted: July 4, 2023
