CFD analysis on hydrodynamic characteristics of ultra-high-pressure water jets: stationary vs. translating nozzle conditions

Engineering Applications of Computational Fluid Mechanics
In the rust removal process via ultra-high-pressure (henceforth UHP) water jet, nozzle translation and rotation significantly affect the jet profile, thereby influencing rust removal performance. Unfortunately, the research on UHP water jets in motion is

Characterization of Droplet Formation in Ultrasonic Spray Coating: Influence of Ink Formulation Using Phase Doppler Anemometry and Machine Learning

Advanced Materials Technologies, EarlyView.
This study explores how machine learning models, trained on small experimental datasets obtained via Phase Doppler Anemometry (PDA), can accurately predict droplet size (D32) in ultrasonic spray coating (USSC). By capturing the influence of ink complexity (solvent, polymer, nanoparticles), power, and flow rate, the model enables precise droplet control
