AbstractCTS-9908442A. Smits, Purdue UniversityThere are many important high Reynolds number turbulent boundary layer flows for which knowledge of the turbulence field statistical properties would be of significant importance to the designer. The velocity field upstream of a submarine propeller and the approach flow forward of the tail rudder on a large aircraft are two examples. Statistical differences and similarities between the largely unexplored high Reynolds number and the well documented laboratory scale boundary layers also have importance for theoretical and modeling consideration within the turbulence community.

摘要CTS-9908442A。普渡大学史密茨有许多重要的高雷诺数湍流边界层流动，对这些流动来说，湍流场统计特性的知识对设计者来说是非常重要的。潜艇螺旋桨上游的速度场和大型飞机尾舵前方的进场流动就是两个例子。在很大程度上未被探索的高雷诺数和实验室尺度边界层之间的统计差异和相似之处，对于湍流社区内的理论和模拟考虑也具有重要意义。
