Abstract

The Keller-Miksis equation (KME) is commonly used for numerical studies of inertial and stable-inertial cavitation. However, experimental validation of KME under clinically relevant exposure settings is scarce, particularly in terms of the acoustic emission signal generated by the cavitation. In this paper, the KME is validated against a cavitation cloud collapsing f0/2 and f0/3 sub-harmonically with some success. This could significantly aid the design of arrays for passive acoustic mapping (PAM), quantification of cavitation dose, and tuning controllers for feed-back-loops.
