Nonmonotonic behavior of the maximum collapse pressure in a cavitation bubble.
Calculations which are relevant to the determination of the maximum collapse pressure generated inside a microbubble as a function of peak pressure in the driving ultrasonic pulse are presented. It is found that above the threshold for transient cavitation, the maximum collapse pressure has a nonmonotonic variation. This result is explained on the basis of phase differences between the external applied acoustic pulse and the resulting bubble response.
