摘要

Sequel the recent advances in computational nanofluid dynamics, the present informative investigation intends to reveal the crucial characteristics of a radiating nanofluidic mixture of alumina nanoparticles and water during its non-homogeneous motion in a porous medium over a convectively heated planar actuator, which is well known by Riga’s plate. Fundamentally, Wakif–Buongiorno’s model is linked theoretically with Darcy–Forchheimer’s law, Gailitis–Grinberg’s findings, Rosseland’s model, and Koo–Kleinstreuer–Li’s expressions to derive realistically the governing partial differential equations under the assumptions of the boundary layer concept and passive nanoparticles’ control point of view. After reducing the mathematical complication of the present physical problem, the simplified differential formulation is tackled numerically in Maple software using simultaneously the midpoint technique and Richardson’s extrapolation procedure. Computationally, it is quantified that the alumina nanoparticles exhibit a strengthening impression on the surface drag forces and heat transfer rate. Also, it is demonstrated that Lorentz’s forces experience a weakening tendency on the augmenting frictional effect of the medium porosity with a reinforcing consequence on Brownian’s motion of nanoparticles. However, an enhancing trend is perceived for the medium porosity and Lorentz’s forces toward the thermal efficiency of the nanofluidic medium at the electromagnetic plate. Furthermore, it is witnessed that the nanofluid temperature distribution and the thermophoresis phenomenon can be boosted extremely by improving the medium porosity, the radiative heat transport, the nanoparticles’ thermo-migration, and the convective heating process.
