不同边界条件下炸药水中爆炸的能量输出结构
Configuration of explosive energy output in different underwater boundary conditions
摘要
Abstract
A series of experiments were carried out to explore the energy output characteristics of the explosive in the different underwater boundary conditions:free field,water bottom,near water bottom and near water surface.The experimental results show that when the explosive is near the water bottom and surface,the boundary conditions weakly affect the explosion-induced shock waves and strongly influence the bubble pulsation.When the distance from the explosive to the water bottom is less than the maximum radius of the bubbles,the underwater explosion of the explosive fails to form an integrated bubble pulsation resulted from the water bottom boundary.When the distance from the explosive to the water surface is less than the maximum radius of the bubbles,the air bubbles overflow the water surface and fail to form the bubble pulsation pressure.When the distance from the explosive to the water surface is 1-1.5 times as great as the maximum radius of the bubbles,partial air bubbles overflow the water surface and the corresponding bubble pulsation pressure is lower than that induced by the explosion in the free field.Because of the air bubble rising in its expansion and contraction processes,the influenced range by the water surface on the bubble pulsation is larger that by the water bottom.关键词
