Thermodiffusion, chemical reaction, and Hall and ion‐slip impacts on MHD rotating flow past an infinite vertical porous plate

Abstract

AbstractThe current scrutiny explores the impacts of thermodiffusion, chemical reaction, and Hall and ion‐slip impacts lying on unsteady heat and mass transport of free convective hydromagnetic flow enclosed past a semi‐infinite porous plate within a gyratory frame under the accomplishment of a transverse magnetic field and convective boundary conditions. The nondimensional governing equations are solved systematically by means of the finite element method. Through the facilitation of graphical profiles, the outcomes of a variety of significant parameters within the boundary layer are addressed. In addition, the local skin friction coefficient and rates of heat and mass transports in expressions of the local Nusselt number and local Sherwood number are presented digitally in tabulation form, although it is originated that the Nusselt number and Sherwood number remain constant with varying all pertinent parameters. It is found that the porous medium impact on the boundary layer growth is significant due to the increase in the thickness of the hydrodynamic boundary layer and the decrease in the thickness of the thermal and concentration boundary layers. The resultant velocity enhances with increasing rotation, Hall and ion‐slip parameters.
