NUMERICAL MODELING AND PREDICTION OF PARTICLE SIZE DISTRIBUTION DURING GAS ATOMIZATION OF MOLTEN TIN
RESUMO
An axisymmetric computational fluid dynamics (CFD) model is developed to simulate molten tin atomization for producing metal powder. A pilot unit with a free-fall gas nozzle is also built to measure particle size distribution from experimental trials. The numerical results are compared with mass percentage and cumulative mass percentage of particle size distribution obtained from experimental sieve analysis of the sampled powder. The model includes two-way coupling of gas-metal interaction, secondary breakup of liquid metal droplets, and subsequent in-flight solidification in the whole atomization chamber. The powder particle size distribution is compared for a range of gas flow rates. The results of the simulation demonstrate the importance of two-way coupling and careful selection of turbulence and breakup models while predicting particle size distribution for the metal atomization process.
