The Role of Cavitation in Droplet Breakup: Understanding and Predicting Hypersonic Structural Loading through Multiscale Simulations and Shock-tube Experimentation
Abstract
The proposed research will investigate the role of cavitation in droplet dynamics following droplet-shock interactions and improve the prediction of this phenomenon. This research will enhance the prediction of rain loading on hypersonic vehicles by illuminating the role of cavitation in droplet breakup. Based on time scale analysis and recent experiments that capture cavitation, there is evidence that except at rather low supersonic Mach numbers, cavitation may be the driving mechanism for breakup as opposed to the commonly assumed surface effects.
