Stability of Flow Through Multistage Axial Compressors [PDF]
Volume 1: Turbomachinery, 1989 This paper describes measurements of the performance of a research stage operating in isolation and as part of a multistage compressor. It is shown that the stall point and the stalled performance of the stage are properties of the system in which it operates rather than a property of the stage itself. The consequences of this for the estimation of the

A throughflow-based optimization method for multi-stage axial compressor
AIP Advances, 2021 A multi-objective optimization tool for multi-stage axial compressors is developed based on an automatically calibrated throughflow method. The Euler-based throughflow equations with blade force terms are solved using a time-marching finite volume method

An Investigation of Spanwise Mixing in Multistage Axial Flow Compressors [PDF]
Volume 1: Turbomachinery, 1992 An equation system has been deduced for meridional throughflow fields of multistage axial flow compressors, presenting different kinds of spanwise mixing effects of the fields in a unified form. The spanwise mixing in compressors is caused by three kinds of effects, molecular motion, turbulent diffusion, and circumferential non–uniformities, the last ...

Aerodynamic design and numerical simulation of mixed-axial flow multi-stage compressor
Zhongguo Jianchuan Yanjiu, 2018 [Objectives] The performance of a gas turbine engine can be determined by the performance of the compressor. As one of the core components of a gas turbine engine,the design of the compressor is of critical importance in the design of the engine overall.[
