Research on Spectral Characteristics of Wake Bubble Curtain

School of Sciences, Xi’an Technological University, Xi’an 710021, China

摘要

摘要: 舰船在行驶过程中, 因螺旋桨的搅动与空气和海水作用产生气泡幕, 最终在船的尾部形成尾流。目前关于尾流光学研究主要集中在以宏观的海面成像判断尾流形状, 以及水下尾流气泡幕的散射特性, 少有学者研究尾流气泡幕的光谱特性。针对此, 文中使用实验室设计的气泡幕发生装置模拟尾流气泡幕, 并分析气泡的变化过程, 包括气泡的大小以及受力情况。利用光纤光谱采集系统获取不同压强条件下气泡幕的透射光谱, 分析了不同压强下尾流气泡幕透射光谱的光谱特性。结果表明, 在不同实验条件下, 透射光谱分布大致相同; 气泡浓度对光谱测量值影响较大, 气泡浓度越大, 透射率越小; 光谱测量值还受不同波段的光在空气中衰减程度不同的影响, 其中长波透射率较大, 所以430~550 nm波段内空气对光的吸收较大, 相比较而言, 600~730 nm波段内的透射率较大。

Abstract: When the ship is sailing, the bubble curtain is generated due to the stirring of the propeller and the influence of the air and sea water, and a wake is formed at the tail of the ship. At present, the research on wake optics mainly focuses on macroscopic sea surface imaging to determine the shape of the wake and the scattering characteristics of the underwater wake bubble curtain. Few scholars have studied the spectral characteristics of the wake bubble curtain. In view of this, the wake bubble curtain was simulated by the generator designed in the laboratory, and the change process of the bubble, including the size and force of the bubble, was analyzed. An optical fiber spectrum acquisition system was used to obtain the transmission spectra of the bubble curtain under different pressures, and the spectral characteristics of the wake bubble curtain under different pressures were analyzed. The results show that the transmission spectrum distribution is roughly the same under different experimental conditions; the bubble concentration has a great influence on the measured values of the spectrum, and higher bubble concentration indicates lower transmission; the measured value of the spectrum is also affected by the different degrees of attenuation of light in different bands in the air. Among them, the long-wave transmission is larger, so the air more absorbs light in the band of 430–550 nm. In comparison, the transmission in the band of 600–730 nm is high.
