Heat Transfer to Half-Ellipsoidal Impeller in Highly Viscous Non-Newtonian Liquids

Abstract

Heat transfer coefficient from a jacket wall to a half-ellipsoidal impeller, which was newly developed by the present authors, was studied in highly viscous Newtonian and non-Newtonian liquids.
It was experimentally confirmed that the impeller was effective in mixing of highly viscous liquid with least power consumption. In particular, an impeller useful as a heat transfer surface gave a high value of heat transfer coefficient.
