射流切向于壁面出现并沿壁面沿着流动的现象长期以来被称为壁面射流。平壁射流和曲壁射流在过去已经被许多研究者研究过。尽管在这一领域的许多调查，一个合理的完整的理解曲率对湍流壁射流的影响尚未实现。因此，本研究旨在作为曲率效应的补充研究。实验是在静止空气中用二维紊流射流在平面和各种半径的圆形凸、凹表面上进行的。该研究仅限于流动的平均特性，而不涉及表面上的动量损失。
The phenomenon of a jet emerging tangentially to a wall and flowing along the surface of the wall has long been known as a wall jet. Plane and curved wall jets have been investigated by many researchers in the past. In spite of many investigations in this field, a reasonably complete understanding of the curvature effects on the turbulent wall jet has not been achieved. This investigation, therefore, was intended to serve as a complementary study of curvature effects. Experiments were performed with a two-dimensional turbulent jet flow over a plane surface and over circular convex and concave surfaces of various radii in still air. The study was limited to the mean properties of the flow and was not concerned with the momentum loss on the surface.
