Droplets stretched by electric stresses emit jets from their pointed tips. We observed in the experiment a new tip-streaming phenomenon by applying a radial electric field to a liquid jet. Droplets in the jet are stretched in the radial direction and develop into a disk-like shape. The growth of non-axisymmetric harmonics leads to the formation of tens of Taylor cones evenly distributed at the equator of a droplet. At the tip of each cone, a tiny secondary jet is emitted, which breaks up into progeny droplets orders of magnitude smaller than the parent ones. This tip-streaming pattern may provide a new spraying route to the generation of micro- and nanosized droplets.

带电液体射流的径向变形和崩解

受到电应力拉伸的液滴从其尖端发射出水流。我们在实验中通过向液体射流施加径向电场观察到了新的尖端流现象。射流中的液滴在径向上拉伸并发展为盘状形状。非轴对称谐波的增长导致形成数十个泰勒锥，它们均匀分布在液滴的赤道处。在每个圆锥体的顶端，都会发射出一个微小的次级射流，该次级射流分裂成后代液滴，其数量比亲代液滴小几个数量级。这种尖端流模式可为产生微米级和纳米级液滴提供新的喷涂途径。
