摘要
在实验室对模拟尾流气泡幕研究的基础上 ,设计了用于真实尾流测试的水下实验系统 通过对千湖 1号船在不同航速下尾流的几何特征进行观察和分析计算 ,得到了尾流深度、宽度与航速的关系 ,并且对尾流的水面宽度以及散开角进行了估计 在 5km/h ,1 0km/h和 1 5km/h的航速下对尾流不同几何部位的激光透射强度进行了测量 ,结果与理论计算基本一致 从透射光的相对强度来分析实验结果 。
Experimental scheme for underwater is designed and manufactured based on the development of wake bubble film simulated in laboratory.Wake depth and width related to the speed of wake ship Qianhu 1 are determined from the observation and analysis of wake geometry of the ship at different rate,the surface width and angle of divergence are specified too.Transmission of laser through different geometrical parts of wakes at three rates is observed.The result is roughly consistent with the theory.Influency of natural light is less important from the point of relative intensity of transmission
