Implication

Critical review links hydrodynamic parameters to cleaning efficiency, erosion mechanisms, and acoustic signals during liquid jet impingement, highlighting acoustic sensing for monitoring.

Key Points

Synthesize experimental, numerical, and theoretical insights on liquid jet impingement to connect fluid dynamics with cleaning efficiency, surface erosion, and acoustic emission.
Reviewed experimental, numerical, and theoretical literature across diverse fluid regimes, stand-off distances, and surface targets.
Collated semi-empirical correlations for cleaned radius, jet breakup length, droplet size distribution, splash ratio, erosion rate, and acoustic frequency spectra.
Cleaning efficiency and deposit removal correlate directly with wall-shear and impact-stress fields dictated by nozzle diameter, jet pressure, flow rate, and stand-off distance.
Material damage is driven by droplet impact, water-hammer pressure, and cavitation, with droplet erosion rates scaling steeply with velocity (e.g., approximately proportional to U^7 in aluminum).
Acoustic emissions spanning from low frequencies to the tens-of-kHz range reflect jet breakup, bubble oscillation, and splashing, establishing acoustics as a viable non-intrusive diagnostic tool.
