9871808 Koseff The project is for a laboratory study of internal-wave breaking. It is proposed to create a wave-breaking event at the interface of a two-layer stratified system, with the purpose of 1) measuring the mixing efficiency of the breaking and the resulting turbulence, and 2) characterizing the fine-scale physical processes associated with the breaking. Three sets of experiments will be carried out: The first two sets will concentrate on visualization of the breaking process, and DPTV will be used in the third set to study the physics and fine-scale structure of the breaking event and the resulting turbulence.

[871808] Koseff这个项目是关于内波破碎的实验室研究。提出在两层分层系统的界面处创建一个破波事件，目的是1)测量破波的混合效率和由此产生的湍流，2)表征与破波相关的精细尺度物理过程。将进行三组实验：前两组将集中于破碎过程的可视化，第三组将使用DPTV研究破碎事件的物理和精细尺度结构以及由此产生的湍流。
