Descriptions
The effect of a trip wire on the development of a two-dimensional turbulent wall jet was investigated by comparison of the flow field between with and without a trip wire near the slit nozzle. Present study is mainly examined from the viewpoints of mean velocity. The available velocity and length scales for the wall jet were proposed, and discussed with respect to the self-preserving. The cross-stream static pressure was measured in detail, we thus obtained dp/dy ≠0.
