Schematics of the experimental rig design. Scheme in A costs less and is relative safe compared to plunger pump, and can be used as a laboratory feasibility test. In this scheme, nitrogen bottle is used as high pressure gas source, and other gas sources can be used instead. B Photos displays the joint fixed in experimental rig. Left, white arrow: direction of jet; Red dotted sqaure, the location of sample. Right, representative image of the cavitation tests on sample
