Centrifugal-force driven flow in cylindrical micro-channel

Micro-channel flow driven by the centrifugal force was studied by analytical and experimental methods. The analytical expression of flow rate as a function of angular revolution speed was applied to the flow under the condition that the increase in frictional loss due to Coriolis force could be neglected. The experimental verification was made by measuring the outlet volume of water through capillaries that were radially mounted. The experimental results show that cavitation can occur in micro-channel flow driven solely by centrifugal force.
