Image represents a Kaplan water turbine runner colored by static pressure. The EnSight vortex core feature is used to emit streamlines. The vortex cores are mainly located in the tip vortex region and in the wakes of the blades. An iso-surface shows where the lowest static pressure is located, which indicates the regions where there is a risk of cavitation damage. Animation courtesy of Håkan Nilsson at Chalmers University.
