Jet characteristics of the three-dimensional explosion bubble in a compressible fluid

In this study, a three-dimensional model for underwater explosion bubble dynamics is established using weakly compressible theory implemented in the boundary integral method. To validate its accuracy and reliability, we compare model's results with theoretical solutions, an axisymmetric model, experimental data. First, systematically study jet characteristics of free field reveal power laws height, width, velocity liquid respect to buoyancy parameter δ. It important note that, addition δ, strength ε also plays significant role determining height jet, particularly when δ≲ 0.3. Furthermore, investigate impact inclined wall on features provide analytical expression angle bubbles near vertical wall, utilizing Kelvin impulse theory.
