Model of the Spray Forming Process
-
摘要: 模擬了噴射沉積過程中的霧化過程;描述了熔滴在飛行中的動力學過程及凝固的熱力學過程;建立了熔滴速度、溫度、固相分數等參數與熔體過熱度、氣流速度之間的計算模型;通過對810℃的液態合金的數值計算,討論了部分獨立參數對該過程的影響.Abstract: The spray forming process is simulated. The in-flight dynamical and thermal histories of the droplets during forming process are described. The relation of the independent parameters such as vilocity, temperature, and solid fraction of the droplets to the melt superheat and the gas velocity is established. Based on the calculation of Al-4.5%Cu alloy, the effect of some dependent parameters on the process are discussed.
