A Numerical Investigation of Porosity and Suction/Injection Effects on Magnetized Slip Flow Affected by Temperature-dependent Property

Abstract

Suction/injection impacts are extremely crucial in boundary layer control, especially in engineering, aerodynamics, space research, and medicine. These benefits prompted our quest to further dig into the effect of wall porosity in industrial working fluids. Therefore, this paper analyzes unsteady magnetized slip flow through an upstanding plate in the presence of suction/injection flow due to the actions of porosity effect and thermal conductivity property. The nonlinear partial differential leading equations are modeled and solved numerically using an unconditionally stable semi-implicit finite difference scheme, while the analytical component of the steady-state equations was calculated using the regular perturbation technique. The solutions obtained were presented and discussed in detail using various line graphs. It is concluded that the Darcy porous, injection, and slip flow parameters promote fluid velocity, respectively. However, a counter-feature can be observed: higher suction and magnetic parameter values lead to a drastic reduction in fluid movement, respectively. The outcomes of this study would be helpful for controlling fluid flow in channels as well as aiding the addition and removal of reactants during chemical reactions.
