Investigation of the centrifugal force effect to a revolving vane (RV) expander.

Number: pap. 1111

Author(s) : SUBIANTORO A., OOI K. T.

Summary

The revolving vane (RV) machine is unique because the cylinder rotates together with the rotor at their respective axis. This causes various unique behaviors that are not previously observed in the conventional rotary machines. In this paper, the effects of the centrifugal force to the behavior of the machine are investigated. It is found that the centrifugal force affects the average output torque through the shaft bearing load and friction loss. Interestingly, if the center of mass is set properly, the centrifugal force can help to offset the pressure force acting at the shaft. This helps to reduce the bearing load and increases the mechanical efficiency of the machine. The finding can be used to optimize the RV machine design.
