Experimental Study of the Cavitation Effects on Hydrodynamic Behavior of a Circular Cylinder at Different Cavitation Regimes

In this work, we experimentally investigated the cavitation effects on hydrodynamic behavior of a circular cylinder at different cavitating flows. We analyzed dynamics behind using high-speed camera and also measured associated forces load cell. studied around various types regimes such as cloud cavitation, partial inception. addition, three Reynolds numbers: 1 × 105, 1.25 105 1.5 105. The results showed that hydrodynamics force can be increased with formation compared inception regime. three-dimensional flow caused complex strong interaction between vortex structures cavity shedding mechanism. revealed number amplitude frequency is significant. However enhancement in constant velocity slightly higher than number.
