Abstract
How cooling fluid pumped axially through a rapidly rotating Taylor-Couette system affects both the heat transport as well as the friction losses inside an electric machine is investigated in this work. The influence of liquid coolants and multiphase sprays affecting the friction losses of the rotating machine is addressed. Methods to increase the heat transport and prevent high friction losses are designed and tested.
