摘要
通过引入水中气泡群分布函数,建立了气幕多体多次声散射模型.与多体一次散射模型相比,多体多次声散射模型能够更加真实地反映出具有较高体积浓度气幕的声散射特性,因此,它是分析声波在气幕介质中反射和透射问题的重要基础.
By use of the dimension distribution of air bubbles, a multi-body multi-dispersion model for bubble screen is set up in this paper. Compared with the multi-body single-dispersion model, the multi-body multi-dispersion model can reflect more actually the noise dispersion characteristics of bubble screen with high volume consistence. Therefore, it is an important basis for analyzing reflecting and transmitting problems of sound wave in bubble screen.
