Abstract
An electro-conjugate fluid is a new type of functional fluid, which can exhibit functional properties in an applied electric field. The application of a high voltage to a pair of electrodes immersed in a certain dielectric fluid induces the occurrence of a strong micro-jet between the positive and negative electrodes. These fluids are called the electro-conjugate fluid, and the phenomenon of the occurrence of the micro-jet is called the ECF effect. We have performed a flow visualization experiment with the 2D PIV analysis. For the case of the cylinder-cylinder electrodes, the maximum velocity of the micro-jet arises on the line connected between the centers of the positive and negative electrodes. A micro-jet occurs at the position of the maximum gradient of the electric field at the surface of the positive electrode and flows toward the largest gradient position of the negative electrode.
