Gas atomization process is based on the disintegration of molten metal to produce metal powders. The disintegration phenomenon is a very complex one to fully understand, and currently, there are no satisfying CFD (Computational Fluid Dynamics) solutions to verify some proposed models. However, that phenomenon has a great impact on the final product and it identifies the characteristics of metal powders. There are a few studies which used different approaches to estimate the particle size and distribution of gas atomization by using CFD solutions with one of the preexisting two-phase models. In this study, interaction of the liquid metal and atomizing gas has investigated via Volume of Fluids (VOF) method of ANSYS/Fluent. This method with a new approach has used to determine the particle sizes and to reveal the atomizing mechanism and characteristics of the gas atomization process.
