装药量对近壁面气泡形态影响的研究
|
摘要
采用AUTODYN模拟对TNT近壁面水下爆炸冲击波传播过程和气泡脉动过程,研究了气泡结构形状、二次压力波和射流现象,发现模拟结果和试验结果一致.比较研究了TNT装药对气泡形状结构的影响,结果表明:在装药较少时,气泡底部射流会刺穿气泡;在装药较大时,气泡上部射流会刺穿气泡;当装药较大或者较小时,气泡为单冠;其他装药时,底侧面射流会切割气泡形成双冠.
Shock wave propagation and bubble pulsation processes of near-wall under-water TNT explosion were simulated by AUTODYN.Bubble shape and structure,second pressure wave and water jet were studied.The result shows that the simulation is experimental results.A set of comparative studies were conducted to explore of the effects of the charge of TNT on bubble shape and structure.Results show that:in smaller-charge condition,water jet at bubble bottom can penetrate the bubble;in largercharge condition,water jet at bubble top can penetrate the bubble;in larger and smaller-charge conditions,bubble is single crown structure;in other condition,double crown bubble is formed,as water jet at bubble bottom side cut bubble into two parts.
