Mixing in Exchange Flows and a New Decoupled Exchange Flow

该项目包括一系列实验室实验， 研究两层交换流中的混合。 这项工作包括 液压控制平均值的定量测量 流动，与不稳定性有关的相干结构的研究 和混合，以及混合对平均流的影响。 连续分层系统将被认为是一旦两个- 层流实验更容易理解。 该研究为混料的研究提供了一种创新的思路 过程;特别是，解耦机制，使流体 在两者之间出现了一层中等密度的层 逆流层和块体的不稳定性和混合。

This project consists of a series of laboratory experiments to study mixing in two-layer exchange flows. The work includes quantitative measurements of the hydraulically controlled mean flow, study of the coherent structures associated with instability and mixing, and the effect of mixing on the mean flow. Continuously stratified systems will be considered once the two- layer flow experiments are better understood. The study provides an innovative idea in the study of mixing processes; specifically, the uncoupling mechanism whereby a fluid layer of intermediate density appears between the two counter-flowing layers and blocks instabilities and mixing.
