This paper deals with an experimental study on the disintegrating processes of a high speed liquid jet injected into the various ambient pressures from a cylindrical nozzle. The effects of the diameter and the shape of the nozzle on the breakup length were investigated by an electrical resistance method. The close dependence between the internal flow in the nozzle and the disintegrating process of the jet were observed using a photographic method. The disintegrating process was divided into six kinds of form. When the disturbance of the liquid flow in the nozzle was very small, the spray flow could not be formed even if the injection velocity was very high at the reduced ambient pressure condition. If both the strong disturbance and the strong interfacical force were given to the liquid jet, the jet could be broke up to the spray flow.
