摘要

This study explores the effects of MHD and slip velocity on micropolar fluid flow, heat transfer and mass transport over a stretching sheet with heat generation. The impacts of heat generation, thermal conductivity, heat flux, micro-rotation, Prandtl number and Schmidt number were investigated analytically. Similarity transformation is applied to convert the governing partial differential equations into a system of nonlinear ordinary differential equations, which are then solved numerically using the bvp4c method. Graphics are used to illustrate the impact of the relevant parameter on the distribution of velocity, micro-rotation, temperature and concentration. Validation of the solutions is done for some specific cases. Additionally, the consequences of several parameters on the skin friction caused by the primary velocity, Nusselt number and Sherwood number are shown in tabular form. A thorough description and summary of the numerical results for key flow parameters, including the local skin-friction coefficient, wall couple stress and local Nusselt number, are presented in tables. Microparticles have a significant effect on the flow phenomenon. The results are interpreted in detail. This research relates to enhancing electromagnetic fluid management, heat exchangers and industrial processes.
