本文导出了在重力和表面张力共同作用下，从转鼓中喷出的无粘液体射流的动力学数学模型，并用渐近法和计算法进行了分析。确定了该射流的轨迹和线性稳定性。利用稳定性结果计算了射流的破碎长度。这种射流出现在使用造粒工艺制造颗粒（例如，肥料或镁）的过程中。在这里，鼓将包含数千个孔，熔融液体将被泵入旋转的鼓中。在射流破碎成液滴后，这些液滴凝固形成颗粒。在这个造粒过程中的射流在重力和表面张力的作用下在空间中弯曲。
A mathematical model of the dynamics of an inviscid liquid jet, subjected to both gravity and surface tension, which emerges from rotating drum is derived and analysed using asymptotic and computational methods. The trajectory and linear stability of this jet is determined. By use of the stability results, the break up length of the jet is calculated. Such jets arise in the manufacture of pellets (for example, of fertilizer or magnesium) using the prilling process. Here the drum would contain many thousands of holes, and the molten liquid would be pumped into the rotating drum. After the jet has broken up into droplets, these droplets solidify to form pellets. The jets in this prilling process are curved in space by both gravity and surface tension.
