Fluctuation correlation of echo from bubbly curtains

  • 摘要: 实验研究了电解气泡幕的回声信号起伏特性,在两种电解电压的条件下,测量了几个频率的信号起伏相关时间,并用声学反演法测量了气泡幕中气泡的体积分数、气泡大小分布以及气泡幕的厚度。
    Abstract: The echo fluctuation from bubbly curtains produced by means of electrolytic method were investigated,of which the correlationtime for several frequencies were measured.Experimental results of volume fraction,the size distribution of the bubbles and the thichness referred to the curtains were obtained by the acoustic inverse method.
