Impact of Non-Newtonian Fluids' Rheological Behavior on Double- Diffusive Natural Convection in an Inclined Square Porous Layer
Keywords:Double-diffusive natural convection, Carreau-Yasuda model, buoyancy ratio, heat and mass transfer, non-Newtonian fluids
In the current study, natural convection is numerically simulated in a shallow, porous, square cavity that is filled with a non-Newtonian fluid. In terms of temperature and concentration gradients (heat and mass fluxes), the active wall was seen as uniform and constant, whereas the other walls are adiabatic and impermeable. To analyze the behavior of shear-thinning fluids, a Carreau-Yasuda model is utilized, which is suitable for many non-Newtonian fluids. It is presummated that the fluid will fulfill the Boussinesq approximation, be laminar, and be incompressible.
