Abstract
A method and device for jetting a pressurized water flow against a material under water to cause cavitation to wash the material. A negative pressure generated by the pressurized water flow is used to draw an air current and mix it into the pressurized water flow. A near-infinite number of bubbles are thus directed to the material through the pressurized water flow. As a result, the control of the water flow controls the movement of the bubbles, and the disturbance caused by the bubbles, the shock wave caused by the bursting of the bubbles, and the turbulent force of the flow serve to wash the material.
