不同设置方式下气泡帷幕对水中冲击波衰减特性的影响
|
摘要
为研究不同布置形式的气泡帷幕对水中冲击波的削减特征,设计了三因素三水平的正交数值模拟试验,并结合敏感性分析的方法分析了气泡帷幕数量、气泡帷幕间距以及气泡帷幕防护距离三个因素对水击波削减作用的影响,结果表明气泡帷幕数量和气泡帷幕防护距离影响较大,多数量且靠近被保护对象的布置形式有利于气泡帷幕对水中冲击波的削减作用。
In order to analysis on attenuation characteristics of shock wave in water was conducted on the bubble curtain with different settings,an orthogonal numerical simulation experiment of three factors and three levels was designed. Sensitivity analysis is designed to analysis on attenuation characteristics of shock wave in water under the influence of bubble curtain spacing,number of bubble curtain and protective distance of bubble curtain. The results show that number of bubble curtain and protective distance of bubble curtain are the key controlling factor of attenuation of shock wave in water was conducted on the bubble curtain. Large number of bubble curtains,as well as near the protected object,is beneficial to the reduction of shock wave in the water.
