Possible Improvement of Output Power of Electro-Conjugate Fluid Flow Generation mediated by Bisected Triangular Prism and Slit Electrode Pair

Abstract

An electro-conjugate fluid（ECF）is a type of functional fluid that flows when a high DC voltage of several kilovolts is applied. In this study, in order to expand the potential of ECF, which is expected to be a power source for microactuators, the shape of the electrode pair is redesigned. Namely, we have divided the triangular prism electrode of the triangular prism and slit electrode pair（TPSE）proposed in a previous study into two parts. To show the effectiveness of the bisected TPSE, the ECF flow was numerically analyzed using a finite element method. The results show that the flow velocity of the bisected TPSE is higher than that of the conventional TPSE. In addition, the velocity distribution of the bisected TPSE confirmed the reduction of flow resistance with the triangular prism electrode.
