A piston impact against a water column charged in a taper nozzle can produce a high-speed pulse water jet. In this paper, we analyze the high-speed pulse water jet with 500[m/s] class in the atmosphere, using CIP method. To verify the computational model, jet photograph by colored Schlieren method and measurement results of pressure changes on the observation chamber are compared with the numerical results. Consequently, collision and break up of jets as well as complicated shock waves around jet are comparatively simulated.
