AB - <p style="text-align: justify;">In this paper, the power-law fluid flows in a two-dimensional square cavity
are investigated in detail with multi-relaxation-time lattice Boltzmann method (MRT-LBM). The influence of the Reynolds number (Re) and the power-law index (n) on the
vortex strength, vortex position and velocity distribution are extensively studied. In
our numerical simulations, Re is varied from 100 to 10000, and n is ranged from 0.25 to
1.75, covering both cases of shear-thinning and shear-thickening. Compared with the
Newtonian fluid, numerical results show that the flow structure and number of vortex
of power-law fluid are not only dependent on the Reynolds number, but also related
to power-law index.</p>
