Abstract: In this paper, the two-dimensional forced convection heat transfer of non-Newtonian power-law fluid flow between two parallel plates filled with partially porous media is studied numerically using the thermal lattice Boltzmann method (TLBM). Shear-thinning (n=0.8), Newtonian (n=1.0), and shear-thickening (n=1.2) fluid are used to investigate the non-Newtonian behavior of power-law fluids. The porous media is prepared by the arrangement of circular obstacles. The effect of Reynolds numbers between 100Keywords: Thermal lattice Boltzmann method; Power-law non-Newtonian fluid; Forced heat convection; Circular obstacles; Porous media (search for similar items in EconPapers)
