Abstract

An electro-conjugate fluid (ECF) is a type of dielectric functional fluid, which generates a powerful flow when a high direct-current voltage is applied. To date, ECF flow has been used in mechanical, chemical and biomedical applications because of its outstanding properties as a micro-pressure source for compact fluid-driven systems. However, the mechanism of ECF flow generation is not clarified and a basic understanding of ECF flow is required to progress ECF applications. We have developed the basic understanding of ECF flow generation through mathematical modeling, and have investigated electrical parameters theoretically. We have clarified microscopically the mechanism for ECF flow generation. We have proven the adequacy of the developed basic understanding by comparing visualized and computed flow characteristics. Furthermore, we have clarified the mechanism for ECF flow generation by comparing ionic transfer and ECF flow.
