Enhanced boiling heat transfer by submerged, vibration induced jets

by Tillery, Steven W.

In this analysis, the efficacy of cavitation jets for heat transfer enhancement was demonstrated. The cavitation jet was formed from a cluster of cavitation bubbles that are the result of a submerged piezoelectric diaphragms oscillating about a given velocity threshold Two different heaters operating in two different flow environments were examined. For each heater in each environment, the cavitation jet significantly increased the heat transfer
