Abstract

In recent years, cavitation is increasingly utilized in a wide range of applications in the biomedical field. Monitoring the temporal evolution of cavitation bubbles is of great significance for efficiency and safety in biomedical applications. Cavitation is characterized by a random phenomenon that causes problems of re-producibility. This could be at the origin of the damage on the vascular walls and the adjacent fabrics of the handled organ. Better control and regulation of the cavitation’s activity during the ultrasonic treatment would establish an inescapable way to envisage the development of a therapeutic device. This thesis work aims at developing a model allowing the regulation of the acoustic cavitation. This improvement could have direct applications in the medical field. This paper presents a theoretical study on the modeling of acoustic cavitation in the medical field and a numerical study of the simulation of acoustic cavitation. The study of acoustic cavitation by current CFD numerical simulations is also of great interest. For numerical simulation, we used OpenFOAM which is a toolbox for the dynamics of computer fluids as free software to access codes and algorithms.
