Development of highly efficient centrifugal-compressor series for turbocooling machines

Abstract

BACKGROUND: Currently, demand for centrifugal-compressor stages with a high pressure ratio is increasing. Such requirements prompt the use of high pressure stages with high circumferential speeds of u₂>300 m/s, which leads to increased levels of conditional Mach number and consequently to pressure losses. Work for stage efficiency increases the energy consumption, and the cooling capacity of refrigerating machine increases.

AIMS: This study aims to develop a series of 10 highly efficient high-head model centrifugal compressors with pressure ratio Π_c=2.0.

MATERIALS AND METHODS: A complex calculation technique developed by the authors is used to increase the efficiency of centrifugal-compressor stages. The method consists of sequential execution of four stages: gas-dynamic calculation, profiling, three-dimensional viscous calculation, and multiparametric optimization.

RESULTS: A series of model centrifugal compressors has been designed with the following range-of-design-mode parameters: conditional flow coefficient is 0,035<Φ<0,12; theoretical head coefficient ψ_t.d.=0,74; and conditional Mach number is 0,93<M_u<0,96. The estimated isentropic efficiency of the developed centrifugal compressors ranges from 77% to 84% depending on the flow rate of the stage.

CONCLUSIONS: A series of 10 highly efficient centrifugal-compressor flow parts has been developed, which can be used in modern centrifugal-compressor gas-dynamic projects.
