Abstract
Different applications of high power ultrasound in industry and medical applications are based on the propagation and collapse of acoustic cavitation bubbles. This paper presents an enhanced numerical model and simulated results of formation and collapse of a single bubble in a liquid for two cases: bubble with uniform pressure and a bubble with variable pressure inside. For the two cases, both heat transfer inside the bubble and heat transfer to the surrounding liquid are taken into account. Various fundamental properties of oscillating bubbles in ultrasonic acoustic field, such as pressure, temperature and velocity fields inside the bubble under the influence of time-dependent acoustic pressure, have been investigated and the results...
