摘要 The bubble dynamic near a rigid wall with a wall jet is investigated by computational fluid dynamics (CFD) method with the volume of fluid (VOF) model, which is validated by previous experimental data. The effects of different velocities of the wall jet and different standoff distances on the bubble dynamics are studied. The results show that the bubble is squeezed with the wall jet due to more force added on the the bubble. When the velocity of the wall jet increases, the wall and the pressure along the wall at collapse time increase because of the extra push induced by the wall jet. As the standoff distance increases, the pressure along the wall first increases then decreases although the distance from the bubble to the wall increases.
