Abstract—

It is shown that the instability of a liquid jet with respect to the external electrostatic field and relative to the presence of the external material medium with common phenomenological features differ by the threshold values of the field parameter and the Weber parameter at which these instabilities are realized for the first two values of the azimuthal mode. For the next, in the order of increasing the number of a bending-deformation mode, both instabilities have the thresholds that differ only by the wave number values at which they are realized. For the mixed electrostatically aerodynamic instability, when both parameters, field and the Weber, differ from zero, the thresholds of instability realization and the critical wave numbers also change.

静电场和气动场对液体射流前三个方位角模式失稳实现规律的影响

摘要-

结果表明，液体射流相对于外部静电场的不稳定性以及相对于具有共同现象学特征的外部材料介质的不稳定性，取决于实现这些不稳定性的场参数和韦伯参数的阈值对于方位角模式的前两个值。接下来，按照增加弯曲变形模式的次数的顺序，这两种不稳定性具有仅与实现它们的波数值不同的阈值。对于混合的静电空气动力学不稳定性，当场和韦伯这两个参数都不为零时，实现不稳定性的阈值和临界波数也会发生变化。
