description: At the moment the compressor equipment range is large enough, but practical application and scientific research degree of a particular compressor type varies greatly. Volume compressors are quite common and they are used in the different industries. One of the volume compressors type is a screw compressor. Screw compressors are compressors that have leading screw and slave screw, the rotation of which is performed towards each other while the space between rotors and casing decreases. Screw compressor operation principle is that couple cavities form between screws and casing, volume of which gradually decreases because of screws rotation and their design features. The work study object is two- rotor screw compressor. The work subject are gaps between a working elements and rotor thermal deformation. The work purpose is to design single stage screw compressor and calculate working elements thermal expansion using numerical simulation in the Ansys software package. The screw compressor design was consisted of heat and power calculation and also the geometric parameters of inlet and outlet window were calculated. Special attention was paid to gaps changes between screws because of thermal expansion calculation. This work was done to compare two methods of screws thermal expansion calculation: experimental and numerical simulation. Based on this we can conclude how relevant is numerical simulation in such problems solving.
