Numerical Analysis on Cavitation phenomena inside the Nozzle with Bubble Nucleation Model

Abstract

It is known that the number of cavitation bubble nuclei increases exponentially as the degree of superheat of liquid increases. Bubble Nucleation Model is incorporated with general-purpose thermal fluid analysis software STAR-CCM+ which set constant number of bubble nuclei. The influence of the change in the number of bubble nucleus on the bubble collapse energy is verified.
