Numerical Analysis of Velocity, Thermal, and Mass Slip Flow in MHD Micropolar Fluid Over a Stretching Sheet with Schmidt Number Effects

This research examines the combined influences of the magnetic field and Schmidt number theoretically on the velocity, thermal, and mass slip flow of a micropolar fluid across a stretching sheet. An appropriate similarity transformation with the boundary conditions was used to alter the governing highly non-linear partial differential equations into non-linear ordinary differential equations. The gained non-linear ordinary differential equations are then solved numerically by the efficient method of shooting iteration coupled with an appropriate order of the Runge-Kutta integration scheme. The impacts of the diverse active dimensionless controlling parameters on the velocity, microrotation, temperature, and concentration profiles are examined, discussed, and presented through graphs. Furthermore, the values of the skin-friction, wall couple stress, Nusselt, and Sherwood numbers are calculated and offered using tables. Results showed that the local skin friction coefficient and the local Nusselt number decreased, whereas the local surface deposition flux increased with increasing thermal slip parameter. It is also depicted that with the increasing value of the velocity slip parameter, the local skin-friction coefficient and the local surface deposition flux decreased. The present solutions are compared with the previous related solutions in the literature in some limiting cases, showing an excellent agreement.
