description: The subject of the graduate qualification work is âInvestigation of the influence of the variation of the geometry oof returning channels on the loss coefficient for high-flow stages of Centrifugal Compressorsâ. This work is devoted to research of design methods for returning channels of stages of centrifugal compressors and optimization of its flow parts. Tasks that were solved in the course of the work: 1. Information review of recommendations and researches of different scientific groups about the design of returning channels. 2. Creation of an optimization parametric calculation of returning channels (determining the geometry to minimize the loss factor). 3. Making recommendations for the returning channels design and formulate a direction for further computational studies. As result, optimized geometries of returning channels were obtained with the minimum of the loss factor for three different loading factors. Flow patterns in meridional and radial planes and graphs of various dependencies were also obtained.
