要約(英語): On the liquid extraction phenomena in which are caused by a nonuniform electric field, the dynamic behavior of the liquids has been investigated experimentally using three working liquids; HFC43-10, HFE7600 and silicone oil. The sphere electrode in air over the liquid surface to the grounded plane electrode in the liquid is used as the experimental electrode configuration. When a positive or negative voltage is applied to the sphere electrode, the distinctive behaviors in each liquid are observed at an air region between the sphere electrode and the liquid surface. In HFC43-10 and HFE7600, the liquid at the air/liquid interface is swollen at just below of the sphere electrode with increasing the voltage. At a certain critical voltage, the liquid is extracted from the top of a swelled liquid and a liquid column between the sphere electrode and the liquid surface is formed instantaneously. Immediately after the formation of the column, the liquid is spouted like a shower from the sphere electrode surface to the liquid surface. The behavior in silicone oil is different from these. After swelling of the liquid, a large liquid drop is extracted intermittently from the top of a swelled liquid and it jumps toward the sphere electrode without the formation of a liquid column. On the other hand, in HFC43-10 and HFE7600, the evaporation of the liquid is accelerated by the applied electric field. The mechanism on these behaviors is discussed qualitatively on the basis of the experimental results.
