喷射成形的雾化气流速度
(北京航空材料研究院，北京 100095)
摘 要: 熔融金属的气体雾化是喷射成形过程的重要组成部分。作者从理论与实验两方面，对雾化气体流场速度和雾化熔滴与气体流场的交互作用进行了研究，建立了雾化气体流速的关系式，探讨了雾化熔滴对雾化气体流场的影响。

VELOCITY OF ATOMIZATION GAS DURING SPRAY FORMING
（Beijing Institute of Aeronautical Materials, Beijing 100095, P. R. China）
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
