Mixing in Turbulent Free Shear Flows Constrained in a Shallow Fluid Layer

8806130将对浅深度流体中的射流和混合层进行实验研究。在这里，通常观测到的有组织涡结构的水平长度尺度远远大于垂直方向上流动的浅深度。这种混合的垂直约束以前没有被探索过，然而这种约束是在各种地球物理和环境混合情况下经常遇到的。热膜和激光风速测量将用于提供速度和浓度场。

8806130 An experimental investigation is to be carried out on jets and mixing layers in a fluid of shallow depth. Here the usually observed organized vortex structures have a horizontal length scale very much larger than the shallow depth of the flow in the vertical direction. This vertical constraint on mixing has not been explored previously, yet this constraint is one very frequently encountered in various geophysical and environmental mixing situations. Hot film and laser anemometry will be used to supply velocity and concentration fields.
