抄録

The purpose of this study is to investigate rheologically complex fluid flow in a Couette-Taylor flow reactor (CTFR) by a numerical calculation. A shear-thinning fluid which can be expressed by Carreau model was selected. The shear-thinning property causes spatial distribution of fluid viscosity in the CTFR. This work, therefore, defined an effective Reynolds number (Re_eff) based on an effective viscosity obtained by a numerical simulation. The critical Re_eff at which Taylor vortices appear corresponded to the critical Re obtained by a linear stability analysis in Newtonian fluids. This means that Re_eff is applicable to predict the occurrence of Taylor vortices in a shear–thinning fluid.
