In electrostatic dispersion of a liquid from a meniscus at the end of a capillary through which the liquid is passed the emitted droplets are unstable with respect to their self-charge and break up, ejecting about 100 smaller (by two orders of magnitude) droplets. However, if the liquid is passed through the capillary under pressure, then, depending on the pressure, there exist ranges of values of voltages applied to the electrodes for which the emitted droplets are stable both with respect to their self-charge and with respect to the external electric field of the system of electrodes. In this paper, the sizes, charges, and specific charges of such droplets are calculated on the basis of the principle of least dissipation of the energy.Translated from Izvestiya Akademii Nauk SSSR, Mekhanika Zhidkosti i Gaza, No. 2, pp. 32–40, March–April, 1991. |
