The water jet flow issuing from the rotating circular pipe with the inclined section has been studied by the method of the flow visualization and the image processing. The velocity distributions and the width of the jet have been measured in the cases of various inclined angles of the section and rotating speeds of the pipe. The effects of these variables on the jet diffusion have been clarified by measuring the jet width obtained from the superimposed images in the plane normal to the jet flow. As a result, it has been found that the jet diffusion is affected by the inclined angle and the rotating speed of the pipe. Furthermore, it has been clarified that there exists the rotating speed showing the effects of the rotating inclined section remarkably.

采用流动可视化和图像处理的方法，研究了斜截面旋转圆管内的水射流。测量了不同截面倾斜角和不同管道转速下射流的速度分布和射流宽度。通过测量垂直于射流平面的叠加图像得到的射流宽度，阐明了这些变量对射流扩散的影响。结果表明，射流扩散受管道倾斜角度和转速的影响。此外，还澄清了转速的存在，转速显著地反映了旋转倾斜截面的影响。
