Multiple slip impacts on unsteady MHD micropolar fluid past a stretching sheet with non‐Darcy porous medium and uneven heat source/sink

Abstract

AbstractThe major scope of this research is to scrutinize the effects of multiple slips on unstable magnetohydrodynamic micropolar fluid past a stretched sheet with a non‐Darcy porous medium. In the momentum equation, the non‐Darcy porous medium effect is also taken into consideration. The effects of uneven heat source/sink and thermal radiation in the energy equation are also analyzed. By implementing the similarity transmission, the mathematical modeling of the set of managing partial differential equations is reframed into nonlinear ordinary differential equations. These equations are numerically solved by applying Matlab built‐in solver bvp5c. The implications of foremost parameters such as micropolar parameter, magnetic parameter, permeability parameter, Prandtl, Eckert, and Schmidt numbers, Chemical reaction, slip parameters on velocity, microrotation, temperature as well as concentration profiles are displayed pictorially and explained. It is worthwhile to mention that the improving values of micropolar parameter escalate the velocity as well as microrotation profiles. However, the upsurge in non‐Darcy porous medium will cause a declining nature in the velocity profile. Also, an enhancement in the unsteadiness parameter brings about a lessening in all the profiles. Increment in all the three usual slip parameters will bring a declining nature in the respective profiles. An increase in Schmidt number will give a deduction nature in velocity as well as concentration profile. Moreover, the physical quantities are defined and Nusselt numbers are formulated in the table, and it enlarges while boosting up and , whilst a reverse nature is noticed for others. This present study compared with the earlier studies in special cases holds a better agreement.
