Comparison Of Gilmore-Akulichev Equation And Rayleigh-Plesset Equation On Therapeutic Ultrasound Bubble Cavitation, Zhong Hu Jan 2013

Comparison Of Gilmore-Akulichev Equation And Rayleigh-Plesset Equation On Therapeutic Ultrasound Bubble Cavitation, Zhong Hu

Graduate Theses and Dissertations

The inertial cavitation of bubble clouds has been considered to be the hidden crucial mechanism for recent new therapeutic ultrasound applications such as Histotripsy and the ultrasound drug delivery. Although many models are already put forward to simulate the cavitation process, due to the inaccessible experimental validation, which model works closest to the real world situation is not well investigated. The objective of this thesis is mainly to compare the simulation performance of the popular Rayleigh-Plesset model and Gilmore-Akulichev model exposed to high intensity focused ultrasound in terms of the bubble equilibrium radius, the ultrasonic pressure, frequency and gas diffusion ...
