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 >

A numerical technique for the nonlinear thermal radiation effect on 3D (“Three Dimensional”) nanofluid (NFs) motion through shrinking or stretching surface with convective boundary condition is examined. In this investigation we use the convective and velocity slip conditions. The governing equations were converted into a set of couple non-linear ODE’s by suitable similarity transformations. The converted nonlinear equations are obtained by applying R-K-F (“Range-Kutta-Fehlberg”) procedure along with shooting technique. The physical parameters are explained graphically on velocity, temperature and concentration. Moreover, we found the coefficient of skin friction, rate of heat tran... More >

This study investigates the combined effects of porous medium properties, nanoparticle dynamics, and fluid characteristics on heat and mass transfer in nanofluid flow through a channel bounded by permeable walls. A comprehensive mathematical model is developed incorporating the Brinkman–Darcy momentum equation, energy and nanoparticle concentration equations, and key nanofluid transport mechanisms such as Brownian motion and thermophoresis. The resulting nonlinear boundary value problem is solved numerically using a robust BVP4C approach in MATLAB. Parametric analyses are conducted to assess the influence of the Schmidt number (Sc), porosity parameter (λ), Darcy number (Dc), Prandtl num... 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 >
