Regular perturbation characterization of transient MHD dissipation penetrable flow with thermal radiative flux

This study investigates the transient magnetohydrodynamic (MHD) flow and heat and mass transfer over an inclined, radiative, and permeable surface under the influence of viscous dissipation and Ohmic heating in a porous medium. A regular perturbation technique is employed to solve the governing coupled, nonlinear partial differential equations that describe the velocity, temperature, and concentration fields. The analysis focuses on key physical parameters, including the skin friction coefficient, Nusselt number, and Sherwood number, along with the corresponding field profiles. The results highlight the significant impact of inclination angle, porosity, and thermal radiation on the transport behavior. Specifically, thermal radiation is found to reduce both the temperature distribution and the Nusselt number, indicating a damping effect on thermal transport. Conversely, the presence of a heat source elevates the temperature while enhancing heat transfer. Additionally, the Soret number contributes to an increase in both temperature and solute concentration due to thermal diffusion effects. The findings correspond well with previously published studies. In other words, when the inclined angle, porous parameter, and radiation parameter are not considered, all outcomes closely resemble those of the previously published works. This study offers valuable insights applicable to various industrial processes, including chemical manufacturing and thermal management systems.
