Development of calculation methods and creation of a compressor with a rolling rotor and with fluid injection for microcryogenic systems

Subject of investigation: compressor with a rolling rotor and with fluid injection. Purpose: development of calculation methods and creation of highly effective compressors with a rolling rotor and with fluid injection for microcryogenic equipment. The work develops a method of calculation of the dynamics of the drops polydispersed flow and their heat-exchange interaction with gas and mechanical interaction with the working surfaces of the compressor based on the n-group approximation; a mathematical model of the working processes of the compressor with a rolling rotor and with fluid injection is developed. The investigation provides a software package of the design calculation and optimization of the main parameters of the compressor with a rolling rotor and with fluid injection. Recommendations are given on the organization of the fluid injection and selection of the main design parameters and characteristics of the fluid to be injected. New design versions are developed to enhance the effectiveness of the above-mentioned compressor operating as part of a microcryogenic system.
