Abstract: This paper presents a numerical study of the behavior of steady generalized Newtonian flows with shearthinning viscosity in a curved pipe. Finite element simulations show in particular that, for sufficiently small curvature ratio and within a certain range of viscosity parameters, the secondary streamlines rotate and the flow field loses symmetry.
