摘要
对波浪边界层厚度提出明确的定义,利用相似原理导出了波浪紊流边界层厚度的合理计算公式;通过水槽实验,包括利用光电调制反馈激光多普勒测速系统(OEMF—LDA),对波浪断面流速分布及边界层厚度进行了量测,获得了大量资料,利用这些资料与作者公式进行比较。二者符合良好。
This paper presents a precise definition of the thickness of wave boundary layer. The thickness equation of the turbulent boundary layer beneath water waves is derived by the principles of similarity. In addition, we studied it through a series of flume experiments. The velocity distribution and the thickness are measured by a new type LDA named Optic Electric Modulation Feedback-Laser Doppler Anemometry System (OEMF-LDA). The theoretical results are in good agreement with experimental data.
