Pulsed Pressure Cavitation Technique (PPCT) is a method to simulate cavitation damage using repetitive pressure pulses [1]. It is developed at Oak Ridge National Laboratory by John Jy-An Wang, Fei Ren, and Yun Liu [2].
The major components of PPCT include a repetitive pulse source and a testing chamber. For examples, a pulsed laser source can be used to generate large shock waves in a confined space. The shock waves then can induce cavitating bubbles [3].
As an emerging technique, PPCT shows many advantages such as small-scale, portable, and more cost effective. It is versatile to perform cavitation study in a controlled environment with well defined temperature, pressure, and chemistry of cavitating media [4].
