Abstract

In hydroelectric equipment, there are many flow situations where the static pressure drops far enough to reach the vapor pressure of the fluid. Vapor- or gas-filled cavities, or clouds of vapor bubbles develop in the regions concerned, and their dynamics has a strong influence on the vibration behavior and flow stability. Due to the wide range of bubble sizes involved, their oscillation and collapse create a wide band spectrum of intense vibration and noise
