本文报道了一类新的微观射流：在一定的物理参数和几何构型范围内，层流加速气流可以形成完全稳定的微观液丝，最终形成几乎单分散的细喷雾。这种强大的和多功能的流动和相关的雾化技术的许多应用程序的一些有趣的特点突出显示。也可以生产同心的多组分液体螺纹。一个理论模型，显示与实验一致。
A new class of microscopic jet flows is here reported: for a certain range of physical parameters and geometrical configurations, a perfectly steady microscopic liquid thread can be formed by a laminar accelerating gas stream, eventually giving rise to a nearly monodisperse fine spray. Some interesting characteristics for many applications of this robust and versatile flow and related atomization technique are highlighted. Concentric multicomponent liquid threads can also be produced. A theoretical model is presented that shows agreement with experiments.
