Conduction and Pumping in Dielectric Liquids under the Influence of an Applied Electric Field

摘要

The main objective of this research was to study the charge injection mechanism from a metal to a dielectric liquid with an applied electric field and also to study the fluid motion and pressure which result from motion of the injected charge. A non-uniform electric field system was constructed and corn oil and silicone oil were used as the dielectric liquid. The experimental results indicate that the current and pressure are the same order of magnitude independent of the polarity of the applied voltage. A new interface potential model was proposed to explain these experimental observations. The experimental results also showed that the similar motion of flow inside the test cell as in the calculation was confirmed by the pressure measurement. (Author)
