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 wavelet multi-resolution method. Three-dimensional views of large-scale structure in the jet cross-section were constructed by applying a volume rendering method to the images of the sum of wavelet levels 1 and 2 in layers in the wavelet multi-resolution analysis. In order to clarify the change with the time of the jet diffusion, the large-scale structure has been investigated in the cases of various inclined angles of the section and rotating speeds of the pipe. As a result, it has been found that the jet diffusion is affected by the inclined angle and the rotating speed of the pipe.
