Robustness simulation of water atomisation

One of the main purposes of water atomisation is to keep the powder size di stribution within a close range. The process is difficult to monitor and th us the state of today's process control is poor. To investigate this proces s, both a laboratory scale and an industrial scale atomisation facility wer e modelled where melt flow and thermal flow were investigated. The results showed that metal temperature is important if stable particle sizes are to be obtained from batch to batch.
