  • Traditional studies on bubble dynamics near solid boundaries mainly focus on its pulsation and jet features near a full plate. A hole will be formed when a warship is attacked by an underwater weapon and it may be subjected to a subsequent attack generated by charge explosion. And the hole on the plate would affect the blow effect of the underwater explosion bubble nearby. To study the bubble pulsation and jet features near a plate with a hole in the middle, a series of experiments is carried out using a spark bubble generator and high-speed camera. We find that when a bubble is generated homocentricly near the hole, cavity-attraction effect of the bubble will be formed due to the effect of the hole, and the opposite-jets can then be formed. Then the influences of dimensionless standoff distance and hole size are analyzed. Finally, the dynamic behavior of a bubble which is generated decenteredly near the hole is studied to show that the blow effect of a bubble increases with decentered position increasing.

Abstract: Traditional studies on bubble dynamics near solid boundaries mainly focus on its pulsation and jet features near a full plate. A hole will be formed when a warship is attacked by an underwater weapon and it may be subjected to a subsequent attack generated by charge explosion. And the hole on the plate would affect the blow effect of the underwater explosion bubble nearby. To study the bubble pulsation and jet features near a plate with a hole in the middle, a series of experiments is carried out using a spark bubble generator and high-speed camera. We find that when a bubble is generated homocentricly near the hole, cavity-attraction effect of the bubble will be formed due to the effect of the hole, and the opposite-jets can then be formed. Then the influences of dimensionless standoff distance and hole size are analyzed. Finally, the dynamic behavior of a bubble which is generated decenteredly near the hole is studied to show that the blow effect of a bubble increases with decentered position increasing.
