The effect of various designs of six-curved blade impellers on reaction rate analysis in liquid–liquid mixing vessel

The mixing efficiencies of impellers vary according to their designs. In this work, the effects of 6-curved-blade impellers of different curvature angles and central disk sizes on the reaction in a stirred vessel were investigated and the results were compared to that of a Rushton turbine. The impel...
