模拟尾流气泡幕中的气泡率及声速

Bubble Proportion and Sound Velocity of Simulated Bubble Film in Wake

文中通过对尾流气泡幕模型的分析与计算,利用伯努利方程计算出实验室模拟的气泡幕的气泡率,针对级联气泡生成装置内部压强、注水深度等参数进行分析,结果表明:在实验范围内,较大压强差会产生较大的气泡率,气泡幕中的声速随气泡率的增大而变慢.

In this paper ,through the analysis and calculation of bubble film in wakes ,the bubble proportion of the simulated bubble film in laboratory conditions is calculated by using the Bernoulli Equation .An analysis is made of the internal pressure and water depth of the device which generates the cascade bubble .The result shows that ,in the experimental range ,a larger pressure difference will produce a higher bubble proportion ,and that the sound velocity in the bubble film decreases with the growing bubble proportion .
