Atomization simulation and preparation of GH3536 powders at different atomization pressures

Fenmo yejin jishu, 2023
Spherical GH3536 alloy powders were prepared by vacuum induction-melting gas atomization method at the different atomization pressures (7, 8, 9 MPa). The region below the nozzle was numerically simulated by multiphase flow model and discrete phase model,
