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

The Investigation of the Stability for Multistage Axial Compressors [PDF]
Volume 1: Aircraft Engine; Turbomachinery, 1985 The “actuator-delay-volume” is used as a physical model for stages of compressors instead of “actuator-lumped volume” model to predict the stability of multistage compressors. The stall line of a multistage compressor is predicted with these two models respectively.

Active Stabilization of Multistage Axial-Compressor Aerodynamic System Instabilities [PDF]
Volume 5: Manufacturing Materials and Metallurgy; Ceramics; Structures and Dynamics; Controls, Diagnostics and Instrumentation; Education; IGTI Scholar Award; General, 1991 Active control of multistage axial-compressor aerodynamic instabilities has been studied analytically using a blade-row by blade-row compression system model. The instabilities considered are those which result from a global system instability.
