327 Effect of Channel Geometry on a Y-shaped Valveless Micropump
Details
Pump characteristics of a Y-shaped valveless micropump were measured to investigate the effect of channel geometry for various branching angle of Y-shaped channel. The test micropumps consisted of Y-shaped channel and a variable volume chamber with a diaphragm which produced oscillating flow. Pump characteristics of four types micropumps were measured for various drive frequencies and volume fluctuations. The experimental results showed that branching angle of Y-shaped channel was effective for the pump performance.
