N2 - The present paper aims to close the gap on the understanding of cavitation model performance with respect to their inherent empirical constants. We first unify several cavitation models, providing a consistent framework for model comparison. Analytical methods are developed to directly compare cavitation models to the Rayleigh Plesset equation. The process is used to (1) develop a method to compare and equivocate models analytically, (2) develop a method to directly assess changes in the cavitation model with respect to bubble dynamics, and (3) provide insight into model improvement. The results identify general physical modeling issues and show that, if the empirical constants are correctly adjusted, the cavitation models yield similar results.
