Abstract

The deformation of a liquid-metal jet in a close-coupled gas atomizers is studied numerically. Here, we employ an explicit two-dimensional multiphase viscous-compressible flow solver, where the volume tracking of interfaces is performed using the M-THINC method. Argon gas is introduced with small incident angles to promote open-wake flows as molten nickel exits from a flat-tip nozzle. Wake configuration and primary breakup are analyzed qualitatively for liquid Weber and Reynolds numbers in the range of 1-40 and 1500-7000, respectively, and for gas-to-liquid momentum flux ratios within 10-900. Liquid-jet disruption tends to occur according to the fountain, the fibrous and the acceleration-wave conceptual models.
