Abstract:Gas atomization of melt metal is an important stage of spray forming process. Through the study of atomization gas velocity, expressions for dimensionless velocity in cross section of atomization gas stream and axial velocity of atomization gas have been established. The influence of droplets on gas velocity was also studied in this paper.
Key words: spray forming; spray atomization and deposition; gas velocity; two phase flow
