The convergence for non-Newtonian fluids to Navier-Stokes equation in 3D domain

In this paper, the convergence of incompressible monopolar viscous non-Newtonian fluids is investigated in 3D periodic domain. We obtain the conclusion that the solutions of non-Newtonian fluids converge to the solutions of Navier-Stokes equation in the sense of L2-norm, as the viscosity goes to zero and the initial data belong to V.
