Abstract:
There are various bubble cavitation phenomena in daily production and life, and near-wall cavitation is the most common one. This paper studies the bubble cavitation dynamics between a rigid wall and an elastic wall, and by changing the distance between the two walls and the initial position of the bubble, several different bubble collapse patterns are obtained. Then, we discuss the changes in the migration distance, gravity, and maximum radius during the cavitation. Finally, numerical simulation is used to successfully acquire the satellite bubbles appearing in the process of the bubble collapse between the rigid wall and the elastic wall, which is in good agreement with the experimental results. We obtained the pressure of the satellite bubble and the elastic wall from the numerical simulation and explained the formation of the satellite bubble.
