Twin screw compressors have been widely used in industry owing to their advantages. Owing to machining imperfections, it is necessary to apply clearance between main and gate rotors, which will still provide minimum clearance with lowest leakage. The aim of this study is to develop a method to analyse clearance distribution between rotors with theoretical, modified design and machined profiles. In order to evaluate contact point on rotors, a localisation algorithm was developed. The clearances were then calculated along sealing line that was originally derived from theoretical profile. The validity of the method was verified by computer simulation and experiments.
