ABSTRACT:
A surge enhanced cavitating jet for a fluid jetting system. The cavitating jet includes a nozzle portion having a conical throat followed by a fluid separating section. Immediately downstream from the separating section is a substantially cylindrical surge section. The length and inside diameter of the surge section are sized such that a minimum annular area is defined between the inside diameter of the surge section and the outside of the fluid stream as the fluid discharges from the cavitating jet such that cavitation is contained in the surge volume. The fluid stream does not impinge the inside diameter of the cavitating jet. A jetting system including a pump and valve is also disclosed.
