HYDRAJETTING NOZZLE AND METHOD

摘要

A method of jetting comprises providing a pressurized fluid to an interior flow path disposed in a nozzle body, passing the pressurized fluid through the flow section in the interior flow path and into the expansion section in the interior flow path, and passing a fluid jet out of the nozzle body from the expansion section, wherein the nozzle operates with a coefficient of discharge between about 1.3 and about 1.7. The nozzle body comprises a flow section and an expansion section, and the expansion section is disposed downstream from the flow section.
