文摘

Study the thermosolutal convection in a porous cubic cavity filled in power-law fluids. Simulate the 3D convection with the compact high order finite volume method. Reveal the shear-thinning fluids is more effective on the change of irreversibilities, heat and mass transfer. Find the effect of heterogeneity level on fluid flow and entropy generation.
