Abstract
This work is devoted to a numerical investigation of three-dimensional gas-vapor bubble dynamics. Bubble oscillations in ambient unbounded fluid and interaction of the bubble with different inclined solid walls are investigated numerically. The fluid is assumed inviscid and incompressible and the flow is irrotational. The boundary-integral method is used as an instrument of numerical investigation. Much attention is paid to the description of a numerical algorithm. Its conservative character is verified by control over conservation of energy. Certain characteristics of the impact jet, which often emerges during the bubble-collapse phase, are investigated numerically. These are the jet height and the direction and velocity of the jet peak. The jet-penetration coefficient is described to estimate the erosion effect on the wall. Dimensional values for different types of bubbles, cavitation bubbles and bubbles formed as a result of different charge explosions are determined
