| Research Abstract |
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.
