High-pressure water jet is used as an instantaneously mixing and emulsifying two kinds of liquids which do not dissolve mutually. In this method, two liquids which mixed beforehand are pressurized and are injected from the small nozzle at high speed. In general, high speed and high shear force of water jet are effective for emulsification. One side, the cavitation bubble which occurred by high speed jet makes the emulsification liquid become cloudy. In this approach, we exhaust the back pressure after injecting from the nozzle, and we showed the relation to the emulsification characteristic by the situation of cavitation bubble. As a result, it was confirmed that the back pressure was effective to the emulsification performance from particle size distribution. In addition, by the fluctuating pressure and visualization in the dispersion chamber under the back pressure, we clarified the break and constrain of the cavitation bubble by the back pressure.
