Numerical Study of Natural Convection in a Corrugated Porous Cavity Saturated with a Nanofluid of Al2O3–Cu/Water Hybrid Type: The Combined Effect of Variable Viscosity and Soret–Dufour Double-Diffusion
This study numerically investigates unsteady natural convection and Soret–Dufour double-diffusion in a two-dimensional sinusoidally wavy porous cavity saturated with an Al2O3–Cu/Water hybrid nanofluid (φ = 0.02), using a Darcy–Brinkman formulation with temperature-dependent viscosity and Rosseland thermal radiation.
