在带电液体射流中，静脉曲张不稳定性导致射流破碎成液滴，而鞭打不稳定性负责射流拉伸。我们表明，这两个不稳定性的耦合和相对重要性决定了射流破碎的结果。横向和径向扰动的共同发展导致显着的破碎模式与初始扰动幅度，扰动波数，和射流电荷水平。
In electrified liquid jets, varicose instability leads to jet breakup into droplets while whipping instability is responsible for jet stretching. We show that the coupling and relative importance of these two instabilities dictates the outcome for jet breakup. The codevelopment of transverse and radial perturbations lead to remarkable breakup modes linked to initial perturbation magnitude, perturbation wave numbers, and jet charge levels.
