Dynamic Behavior of Bubble near Vertical Plate in Underwater Explosion

Abstract:

In this study, the volume-acceleration model was introduced to determine the initial condition for bubble motion during underwater explosion. Subroutines, which defined the initial and boundary conditions of the fluid field, were developed based on MSC.DYTTAN software. Numerical simulations were compared with the results of validated experimental data. From the basic phenomenon of interaction between a bubble and a vertical rigid wall, the dynamic behavior of a bubble near a vertical rigid wall was simulated and analyzed. The dynamic behavior of bubble and the jet were studied systematically and summarized relative to the law that both of the motion of bubble and water jet are closely related with the standoff distance parameter. The results of this study have valuable implications for correlative theory research and engineering calculation.
