Abstract

The performance of twin-screw compressors is primarily affected by the clearance between the pair of meshing rotors. This study proposes a numerical method for meshing clearance evaluation (MCE) for screw rotors, using two normal rack curves that are generated by the discrete male and female rotor profile points. The calculated results are then compared, using the HOLROYD Profile Management System (HPMS) software, in order to verify the correctness. Additionally, clearance band variation with the rotation angle is considered in the compressor performance simulation, to assess the influences on the compressor efficiency.
