| Abstract Scope |
Metal powders used in additive manufacturing can be produced via different methods. The size distribution of gas-atomized liquid metal is of great interest due to its effects on powder quality and on the density of the manufactured product. The main objective of this study is to investigate the feasibility of using the Lubanska correlation to predict the particle median size of the metal powders. The study utilizes MATLAB software to develop a numerical model that is capable of predicting powder size distributions and of taking into consideration the parameters that influence the gas atomization process and the gas-solid two-phase flow. To fully describe the particle distribution, the study investigated two characteristics: Mean droplet size, and geometric standard deviation to estimate the spread of particle size about the mean value. Comparison with the existing experimental data provided useful data regarding the utility of the Lubanska correlation in prediction of powder sizes. |
