Centrifugal compressor of a prospective gas compressor unit: selection of parameters and sample project compressor

Presented is the analysis of the optimal rpm and number of compressor stages. In the framework of the project “The creation of modern hi-tech production of design, production and installations tests, has compressing gaseous products for effective use in transport systems and technologies” - grant the Ministry of education and science of the Russian Federation on the basis of RF Government decree No 218 a laboratory “Gas dynamics of turbo machines” JIST SPbPU has developed a methodology and computer software intended for advanced centrifugal compressors design. The program complex was used for geometry optimization of “Iskra-Avigaz” centrifugal compressors, and also for design of the 25 MW compressor. Taking into account the existing trends in the development of compressor and modern experience, “Iskra-Avigaz” developed the design of the compressor and made the characteristics binding to the specified parameters in the 2nd - 4th lines the North European pipeline. The high efficiency of application of the prospective compressor is shown.
