Numerical Simulation of a Close-Coupled Atomizer: Prediction of the Particle Size Distribution

Dr. Vogl will present a novel two-phase model based on the so-called Eulerian–Lagrangian Spray Atomization (ELSA) method to simulate the interaction of hot liquid metal with a high-speed gas jet. The results of the simulation of the two-phase systems (water-air on one side and liquid steel-argon on the other side) will be presented. The predicted droplet-size distribution will be compared with experimental results from the metal powder production plant at SMS Siemag.
