Charcteristics of Hydraulic Capsule Transport

Abstract

The motion of capsules was numerically analyzed using the method of characteristics. It was found that the velocity of a capsule with large mass is lower than that with small mass, and that collision occurs when capsules of different masses are loaded into pipeline under a lower inlet pressure head. Time histories of pressure were also examined near the capsule loader and near the outlet of the pipeline. To confirm the numerical analysis, measurements in a horizontal pipeline were carried out using capsules of different masses. The numerical solution shows good agreement with the measurements.
