Functional fluid containing diamond particles generates the peculiar microscopic flow pattern with some rotational flows in the gap of electrodes under high voltage alternating current electric field. Their microscopic flow characteristics influenced by particle density and solvent viscosity were investigated with the measurement of a micro particle image velocimetry and the observation of a microscope. This functional fluid has four types of flow structures and shows five patterns of particle clusters. In particular, the rotational flows are typically generated under high electric field and low current frequency against any particle density conditions (l〜8wt.%) except the low particle density condition (0.2wt.%). Furthermore, the solvent viscosity condition affects the characteristics of the flow pattern.
