Impact of a solid on a liquid jet

Theme :  Cavitation

The Pelton turbines are driven by a liquid jet impacting the bucket of the turbine to produce the mechanical torque. The impact is so violent that in some cases shock waves appear in the water. These shock waves are responsible for the formation of cavitation bubbles in the bucket of the turbine and the collapse of these bubbles induces erosion. The aim of this project is to investigate the shock waves and cavitation bubbles formation at the impact of a solid on the liquid jet. The existing experimental setup will be improved in order to perform high speed visualizations within the water jet.
