Abstract:
When cavitation bubbles are set to grow in a liquid, they may implode violently emitting high speed jets and strong shock waves. Cavitation bubbles are therefore the source of serious erosion damages in hydraulic machines such as pumps, turbines or ship propellers. Yet the physics behind the erosive process is still not fully understood. We present here a review of experimental investigations conducted at EPFL‐LMH in the past 5 years involving the following aspects:
• Bubble dynamic within liquid drops;
• Cavitation induced by high speed impact of a solid on a liquid jet and its implication on Pelton turbines;
• Effect of pressure gradient on cavitation bubble dynamics.
These studies were mainly performed in EPFL high speed cavitation tunnel and aboard Zero G flights with the collaboration of the European Space Agency. We will focus on peculiar phenomena that we have discovered and which help to better understand the erosion mechanism in hydraulic turbines.
