Ultrasonic vibration was applied to plug conveying line, and pressure drop was measured. As a result, pressure drop became smaller linearly with increasing of ultrasonic amplitude regardless of particles and flow conditions. Therefore, ultrasonic can reduce the frictional resistance between particles and pipe wall. Additionally the wall pressure was measured by the button sensors, and relation of reduction effect and wall pressure was examined. Reduction effect becomes smaller as wall pressure becomes larger in spite of kinds of particle. Therefore, it is possible to predict the reduction effect by ultrasonic.
