Electro-conjugate fluid (ECF) is a kind of dielectric fluid, which generates a powerful jet flow when electrodes inserted into it are subjected to high DC voltage. Presently, several different electrode pairs have been developed. In order to combine high performance with easy fabrication of the electrode pair, a triangular-prism-slit (TPS) electrode pair has already been proposed. In this paper, a novel ECF-jet generator capable of adjusting alignment and gap of the TPS electrode pair is designed to investigate the influence of structure parameters on its performance. Using this generator when one parameter is set successively at different values, the other parameters can be manually regulated to keep constant, and accordingly interference caused by fabrication and assembly error on experiments is overcome. Under different parameters, including slit width, triangle tip angle and electrode gap of the TPS electrode pair, the output pressure and the flow rate of it are tested and the relationships between performance and structure parameters are obtained.
