ROLE OF NON-CONDENSABLE GAS ON CAVITATION INCEPTION

Abstract

Cavitation is a liquid-vapor phase transformation that occurs as a result of depressurization. Despite extensive research, fundamental aspects of cavitation still escape our understanding. This has tangible consequences for the US Navy, e.g., control of acoustic signature, wear on propellers, etc. In particular, non-condensable gases dissolved in water are crucial for cavitation, but a mechanistic understanding of their role on the inception process remains elusive. This can be partially attributed to the absence of a first-principles model for cavitation with non-condensable gases and to the challenges in measuring the non-condensable gas concentration in cavitating environments.
