| Research Abstract |
The development of the micro pump is important because it is related to the fuel supply system of the micro-machine. In micro area, the Reynolds number is extremely low, and the method of using the viscosity is effective for the rotation type pump. In this research, a new viscous micropump using rotor with groove is proposed. Its pressure characteristics are investigated by using a theoretical analysis and a model experiment. In the theoretical analysis, the two-dimensional lubrication theory for a straight duct is adopted. In the model experiment, the low Reynolds number flow in practical micropumps is realized by using glycerin as working fluid, and a centimeter-scale (not micrometer-scale) model pump is examined. With respect to the pressure characteristics, the theoretical results show qualitative agreement with the experimental ones. The pressure at zero flow rate obtained is quite larger than that of an existing viscous micropump.
