Visualization Technique of Rotating Wing wake
旋转翼面尾迹的流态显示技术

A visualization technique of rotating wing wake is presented. This method is based on a conventional smoke wire technique. A special smoke generator, which rotates together with the wing, is used to visualize the wake. With this smoke generator, not only the density but also the generating time of smoke are increased. The flow pattern visualized with this technique can be used to illustrate the character of rotating wake qualitatively.
