| Description |
To harness the destructive forces
of cavitation erosion in a water jet nozzle for cleaning underwater structural joints. |
| Progress |
Complete. A hand-held, gun-like
device was tested by divers on an offshore navigation structure. Cleaning rate to bright
metal on 6-year marine growth was 1 square foot per minute. Slight thrust from the jet was
experienced, there was not much turbulence in the water to obscure the divers' view. If
manufactured for production, the luger-like device needs to be lightened to about one-half
its present weight, which appears feasible. |
