Abstract
Cavitation occurs when a fluid is subjected to near-vacuum pressures which causes homogeneous nucleation inside the fluid. This phenomenon can be observed with the formation of bubbles which collapse after a short period of time and have the ability to inflict damage on surfaces. With a critical Cavitation number equal to the number one, varying fill heights will have an impact on whether cavitation does or does not occur. Prior research shows that, with increasing fill height, the cavitation number would decrease below critical, causing more cavitation. The goal of this experimentation is to further examine this relationship between fill height and cavitation number using a new, high-speed camera. In addition, the effects of the cavitation on the equipment and testing apparatus are also studied.
