Heat Transfer and Mixed Convection Flow of Non-Newtonian Thermo-Dependent Power Law Fluids with Thermal Radiation Effect

The current study explores numerically mixed convection of thermo-dependent power-law fluids in a square lid-driven enclosure, including the thermal radiation effect. vertical sidewalls are sustained at both hot and cold temperatures. On other hand, cavity is insulated from horizontal walls. upper wall moving along x-axis. main governing equations that Boussinesq approximation used for solved using finite difference method. simulations focus on effects multiple pertinent parameters, Richardson number. (Ri = 0.1, 1, 10 100), parameter (Rd 0 10), index (0.6 ≤ n 1.4) Pearson number (0 m 6). findings reveal improving reduces heat transfer. Then, increasing Rd results domination conduction fluid having higher conductivity. Also, growth power law-index transfer while convective flow. Finally, improves flow rate also average Nusselt
