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

8806130 将对射流进行实验研究， 在浅深度的流体中混合层。 这里通常 观察到的有组织的涡旋结构具有水平长度 规模远远大于浅的深度流在 垂直方向。 这种对混合的垂直约束 以前已经探索过，但这种限制是一个非常 经常遇到的各种地球物理和环境 混合情况。 热膜和激光风速计将用于 供给速度场和浓度场。

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.
