The adiabatic and volumetric efficiencies are key performance parameters of any positive displacement machines including twin screw compressors. These efficiencies are affected by clearances and leakages in these machines. The leakage happen because of clearance gap and pressure difference between two pressurized chambers the compression module. In this work, findings from all the numerical and mathematical models are presented for different leakages in the twin-screw compressor. Authors proposed an iterative method to estimate the leakages by taking in account the geometry of the clearance, friction and local resistances. An experimental set up to collaborate the leakage model is presented, which can be used for further investigation of these leakages.
