Abstract
The present research proposes a new type of viscous micropumps that has a rotating disk integrated on the upper wall of the elbow rectangular duct. The pressure performance of the viscous micropump was experimentally investigated. The performance of the micropump was evaluated from the flow rate and the pump head simultaneously measured by the electronic balance. The Reynolds effect was also estimated by changing the rotational speed. The pressure characteristics are represented as a straight line with a negative slope in the relation between the flow rate coefficient and the product of the pressure coefficient and the Reynolds number, which are the similar characteristics to the conventional viscous micropumps.
