摘要：
The hydrodynamic characteristics in a continuous rotor-stator mixer (CRS) with Newtonian and Non-Newtonian fluids were studied experimentally, and three different stators were used in the experiment. The power characteristics and Kolmogorov scale were measured and analyzed. The results show that the power number of stator type 3 is larger than that of stator types 1 and 2, the value is 5.44. The Metzner-Otto constant of CRS is larger than that of normal impellers. The Kolmogorov scale in the CRS is an order of magnitude smaller than that in a traditional stirred tank, so the CRS offers much shorter micro-mixing time than stirred tanks. The results are of importance to the optimization of industrial continuous rotor-stator mixers.
