Interaction between high-velocity gas and liquid in gas atomization revealed by a new coupled simulation model
Materials & Design(2021)
摘要
•The gas atomization process is first modeled by combining the volume of fluid model with dynamic adaptive mesh and the discrete phase model.•The formation of the powders and the evolution of the defects are simulated.•The reasons for the formation of several typical defects are analyzed.•The possible measures to reduce the defects of the powders have been put forward.
