The porosity parameter serves as a pivotal factor in determining the resistance exerted by a porous medium on fluid motion, especially in magnetohydrodynamic (MHD) flows. This study presents a novel numerical investigation of the coupled influence of porosity, viscous dissipation, and Joule heating on both momentum and thermal boundary layers over a porous surface. The results demonstrate that increasing porosity enhances medium permeability, thereby reducing hydrodynamic drag and intensifying the velocity gradient near the stagnation region. Conversely, lower porosity impedes fluid penetration, resulting in diminished velocity and a compressed boundary layer structure. While the direct impa... More >

This study describes convective temperature and mass transport in a magnetohydrodynamic nanofluid moving via an absorbing channel stretched across an extensive region while being influenced by a securing region. The analytical framework incorporates a multitude of factors including heat generation, thermal radiation effects, viscous dissipation, and chemical reaction implications. The influences of porosity, warm production, thermal emission, attractive fields, sticky indulgence, and substance reactions on the flow dynamics are absolutely expounded across a spectrum of governing parameters. Furthermore, it is posited that regulation can be applied to the nanoparticle volume segment at the bo... More >
