Краткое описание

Numerical simulation of the Newtonian heating effect on unsteady magnetohydrodynamic (MHD) flow of Casson fluid past a flat vertical plate has been carried out considering the impact of viscous dissipation, Joule heating, thermal diffusion, and nth order chemical reaction. The fluid flow in porous medium is induced due to non-torsional oscillations of the plate and the thermal and solutal buoyancy forces acting along the length of the plate. The governing flow equations are converted into dimensionless form using appropriate non-dimensional parameters and variables and then numerically solved by implementing implicit finite difference scheme of Crank–Nicolson type. Behavior of the flow characteristics under the actions of various regulatory flow parameters have been discussed with the help of graphs and tables. One of the important findings of this analysis includes that an intensification in the Newtonian heating effect causes a gradual downfall in the rate of heat transfer at the plate. The kind of investigation we have done here may find several industrial and medical applications such as in paper production, glass manufacturing, purification of crude oil, and study of blood flow in the cardiovascular system, etc.
