抄録

A valveless micropump has been developed with a diffuser/nozzle shaped channel and a variable volume actuator which produces an oscillating flow. The pressure-loss in a nozzle is lower than that in a diffuser, therefore one-way flow is considered in the nozzle direction. Frequency characteristics were determined. Simplified 1-dimentional analysis was done for unsteady operation of the pump by considering the channel geometries and pressure loss coefficients based on unsteady Bernoulli's equation under the assumption of quasi steady flow. 3-dimentional calculations were done using the commercial CFD. The calculated pump characteristics agreed with the measured ones for lower drive frequency. The measured and calculated results were rearranged using dimensionless numbers considered the direction, and compared the pump characteristics to understand the physical mechanisms of the micropump.
