Numerical Study of Thermophoresis on Mass Transfer from Natural Convection Flow over a Vertical Porous Medium with Variable Wall Heat Fluxes

This study investigates heat and mass transfer under natural convection flow along a vertical permeable surface with variable wall fluxes through porous medium. The non-Darcian model is employed for the effects of suction/blowing, inertia, buoyancy ratio, exponent flux, position parameter, Schmidt number, thermophoresis are considered. governing equations continuity, momentum, energy, concentration solved by adopting similarity transformation Runge–Kutta integration shooting technique. Results interest, such as velocity, temperature, profiles related to local Nusselt Sherwood numbers, obtained selected ratio at different magnitudes thermophoretic effect. numerical solutions help us realize gas diffusion phenomena control transport technology.
