IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

PROPELLER BLADE IMPACT FORCES DUE TO CAVITATION CLOUD COLLAPSE BY USING A COUPLED EULERIAN-LAGRANGIAN METHOD
Author : Ville S. L?ms?, Juha Virtanen, Aki Kinnunen and Pekka Koskinen
Cavitation is a significant cause of wear, noise and loss of efficiency in marine propellers. In this study the impact forces due to cavitation cloud collapse are investigated in context of icepropeller interaction. Force measurements from the propeller blade indicate that the hydrodynamic non-contact forces are relevant when the loads on the blade are developed during the ice-propeller interaction. According the measurements one could claim that the measured short duration force peaks are due to cavitation cloud collapse. These cavitation clouds originate from the previous blade while milling the ice block and collapse once arriving on the pressure
