为了解超声速欠膨胀射流激波啸叫噪声的产生机理,基于宽高比10∶1的矩形收缩喷管射流模拟实验装置,采用远场噪声测试及近场流动纹影测量相结合的方法,研究了超声速射流激波格栅结构的非定常运动规律,及其与大尺度旋涡相互作用产生啸叫噪声的过程。实验结果表明不同方位激波啸叫噪声的产生机制存在差异,射流上游和侧边方向的激波啸叫主要是由大尺度旋涡与激波格栅尖梢相互作用而形成的弧形脉冲声波,而下游方向的激波啸叫噪声主要由马赫波辐射引起。实验探究了超声速射流激波格栅结构的非定常运动激发激波啸叫弧形脉冲波的过程,并采用高斯调制的弧形脉冲序列对激波啸叫噪声进行模拟。结果表明,激波啸叫弧形脉冲声波的离散性质以及多声源机制会导致高阶激波啸叫噪声的产生。

A neritid species Vittina pennata （von Born, 1778） is reported for the first time from the South China Sea. This is also the first report of this genus from Chinese waters. The specimen was collected from the Sanya Harbor, Hainan Province, China and deposited in Marine Biological Museum, Chinese Academy of Sciences. Detailed descriptions of its shell feature are presented. Differences between this species, Vittina coromandeliana and Neritina pulligera are compared and discussed.
