Numerical Simulation and Characteristics Study of Near-Field Fan Jet Breakup in Airless Spraying

The breakup process of near-field jets in airless spraying directly determines the initial droplet size distribution and macroscopic spray pattern, making it a critical factor af-fecting coating quality. This study establishes a numerical model for near-field atomi-zation based o...

Numerical and Experimental Investigation of Dynamic Air-Assisted Spray Deposition Characteristics on Horn-Shaped Surface

To address the challenge of uneven coating deposition during air-assisted robotic spraying on horn-shaped surfaces, a gas–liquid coupled numerical model was developed using the Euler–Euler multi-phase flow approach and subsequently validated through experimentation. Two dynamic s...
