摘要
本文以声波散射理论为基础,建立了二维情况下水中气泡在平面声波的作用下的声场分布情况的声场模型。分析了入射声波频率为500k Hz时,不同气泡半径对声场分布的影响,结果表明气泡的半径越大散射声场越强。气泡前声场强于气泡背后声场。并运用散射声压与气泡半径的关系计算出气泡的半径。
In this paper, based on the acoustic scattering theory, established a two-dimensional cases under the action of the water bubble in plane sound wave sound field distribution of acoustic field model. Analyzed the incident sound wave when the frequency is 500 k Hz the influence of different bubble radius on the sound field distribution, the results show that the more the greater the radius of bubble scattering sound field. Bubble sound field is stronger than before the bubble behind the sound field. And using the scattering acoustic pressure and the relationship between the bubble radius to calculate the radius of bubbles.
