Abstract

Conventional pumps include sliding parts and there is a limit of life time due to friction and wear. To solve this problem, a number of pumps using ultrasonic vibration have been proposed. In the present study, we found an occurrence of pump effect when an opposing block faces ultrasonically vibrating surface with small gap. According to the measurement results of gauge pressure, when circumference of the opposing block is tapered, fluid was discharged from the gap of two surfaces. On the other hand, when center of the block is tapered, fluid was sucked in the gap. This paper reports experimental results of the pump effect.
