Summary

For a dry compressor, internal leakage losses are always significant due to the absence of lubricant. In this paper, a simulation study focuses on the leakage through a rotary swing compressor rotor endface clearance is presented. Leakage is found to increase during the compression process and decreases when discharge process starts. Due to the complexity of the rotor geometry, the leakage simulation is carried out by using a CFD computational code under different operating conditions and the results are then used to be an input to the lumped simulation model to analyze the compressor’s overall performance. With this approach, a lumped numerical simulation model is successfully simplified.
