9505628 Melville Evidence suggests that dissipation due to turbulence in a shallow mixed layer in the presence of surface waves is larger than that in a comparable solid-wall turbulent boundary layer by as much as two orders of magnitude. In this project, the PI will develop an improved method for measuring turbulent dissipation under breaking surface waves, using a single beam acoustic Doppler profiler. ***

梅尔维尔有证据表明，在表面波存在的情况下，浅混合层中由于湍流引起的耗散比可比较的固体壁湍流边界层中的耗散大两个数量级。 在这个项目中，PI将开发一种改进的方法，使用单波束声学多普勒剖面仪测量破碎表面波下的湍流耗散。 ***
