Thermosolutal mixed convection of a shear thinning fluid due to partially active mixed zones within a lid-driven cavity

In this paper, a generalized forced convective flow inside a cubical enclosure filled with a non-Newtonian power-law fluids is carried out numerically. The flow is influenced due to a discrete temperature and mass gradients along its short side walls. The non-Newtonian fluid considered here are described by the power-law model (also known as the Ostwald-de Waele model), which leads to a relationship between the shear stress and shear rate. The fluid is assumed to be laminar, incompressible and suppose to satisfy the Boussinesq approximation. A detailed physical insights into the flow, heat and mass transfer effects due to the different physical parameters such as Reynolds number (0
