The siphon phenomenon is widely used for the transportation system of water and it is very economical and ecological because the natural energy of water is only used for the power source of the transportation system. The siphon phenomenon is continued while the water is supplied with from the entrance, and a large-scale separation flow forms near the entrance of a siphon tube. The appearance, the growth, the movement and the disappearance of a swirling vortex are observed inside the siphon tube, and the flow field near the entrance becomes very complex. In the present paper, the flow pattern behind a sharp edge of the entrance was investigated experimentally using the PIV measurement.
