Fine metal particles produced by gas atomization are recognized as an essential material for additive manufacturing. However, spatio-temporally resolved images for the atomization process are still lacking. In the present study, we apply a high-speed

Turbulence is one of the most important phenomena in fluid dynamics. Large eddy simulation (LES) generally allows us to analyze smaller eddies than when using simulations based on unsteady Reynolds-averaged Navier–Stokes equations (URANS). In addit
