The siphon phenomenon is widely used for the transportation system of water and it is very economical and easy on the environment because the natural energy is only used for the power source of the transportation system. In the present paper, the feature of a siphon phenomenon induced by a water jet was numerically and experimentally investigated. In order to investigate the influence of jet velocity and flow passage configuration, numerical simulations were carried out for three kinds ofjets and four kinds of tube configurations. From computational results, the jet velocity was strongly influenced for the appearance of the siphon phenomenon. The configuration of the flow passage was clearly influenced in the case of slow velocity of the water jet. When the orifice location was low, the appearance of the siphon phenomenon became early. The similar tendency was also obtained from the experimental results.
