Numerical simulation of spraying aluminum/tin in an INEL delaval spray-forming nozzle
- Idaho National Engineering Lab., Idaho Falls, ID (United States)
The two-phase flow in a gas atomizing, liquid metal spray nozzle is simulated using both an Eulerian-Lagrangian and an Eulerian-Eulerian analysis. The Eulerian-Lagrangian analysis couples a linearized block implicit Navier-Stokes method for the gaseous phase with a Lagrangian analysis for the droplet phase, resulting in an efficient scheme for the computation of poly-dispersed two-phase flow. The motion of the droplet phase is tracked in the computational coordinate space, resulting in improved computational efficiency; the interphase coupling terms are computed from the instantaneous distribution of the droplets rather than from trajectory information. The Eulerian-Eulerian analysis is performed using an explicit Flux-Corrected Transport (FCT) technique which closely follows the FCT development of Boris and Book. With this approach, the solid phase is treated as a pseudo-fluid continuum resulting in a rather simplified approach to modeling a dispersed two-phase flow.
