| This paper presents an experimental investigation of water jet velocity and kinetic energy under conditions representative of abrasive water jet machining of CFRP/AI/CFRP hybrid structures for aerospace applications. Jet dynamics were recorded with a Phantom V1610 high-speed camera for operating pressures of 200, 300, and 380 MPa. Image analysis performed in TemaMotion enabled determination of jet velocity in a calibrated measurement zone and comparison with a Bernoulli-based theoretical model. The results showed an increasing trend of jet velocity with pressure, from 380 to 430 m/s, accompanied by a pronounced increase in jet kinetic energy. High-speed observations revealed three characteristic flow regions: the region directly below the nozzle, the intermediate jet-development region, and the water-surface interaction region. Higher pressure produced a longer coherent core, stronger jet spreading, and a wider interaction region. Although experimental velocities were lower than theoretical predictions, the same monotonic trend was observed. The obtained results provide a quantitative basis for further studies on surface quality and interfacial damage in AWJ machining of multilayer aerospace composites. |
