摘要：应用平面和圆柱液膜破碎的波理论研究了旋转盘离心雾化膜状分裂区的粉末尺寸的预测方法;推导了最快增长的液膜破碎的波数方程,建立了旋转盘外液膜厚度与液膜径向位置的关系,并用数值方法进行了求解;计算的液膜破碎长度和粉末粒径与文献中的实验数据基本吻合,表明本文所提出的预测方法是可行的。
The wave theories of sheet and circular jets were applied to analyze the disintegration of metallic melts in film formation regime during centrifugal atomization by rotating disk. The equation for the fastest growing wave number was derived and solved numerically. The relationship between the film thickness and the film radial position was established. An integrated model is proposed to calculate powder particle size in FF regime. The agreement of predicted film length and powder particle size with experimental results reported in the literatures indicates that the wave theory can be used to predict powder particle size in FF regime with a reasonable accuracy.
