Inertial Cavitation and its Relationship with Fluid Fill Height

Cavitation occurs when a fluid is subjected to near-vacuum pressure caused by high acceleration of the container, which leads to homogeneous nucleation inside the fluid. This phenomenon can be observed with the formation of bubbles which collapse quickly. It is therefore of significant interest to study this phenomenon due to the bubbles ability to inflict damage on surfaces. An equation can be used to determine whether cavitation occurs. In this equation, the likelihood of cavitation to occur can be represented by the cavitation number "Ca." Cavitation occurs when the value of "Ca" is less than 1 and does not occur when the value of "Ca" is greater than 1. The relationship between the acceleration of the fluid and the fill height of the container determines whether cavitation occurs. Prior research indicates that, with increasing fill height, the cavitation number would decrease below critical, causing more cavitation. The goal of this research is to determine if the relationship between fill height is proportion or inversely related using a new, high-speed camera. In addition, the effects of the cavitation on the equipment and testing apparatus are also studied.
