Axial Location of Casing Treatment in Multistage Axial Flow Compressors
Volume 6: Turbo Expo 2005, Parts A and B, 2005Koch in Ref. 1 presented a procedure for estimating the maximum pressure rise potential of axial flow compressor stages. When used in conjunction with a stage stacking off-design performance prediction method, it can indicate which stage is likely to be responsible for stalling a multistage compressor.

Simulation of Surge Inception and Performance of Axial Multistage Compressor
Volume 6: Turbomachinery, Parts A and B, 2006This work concerns transient multistage turbomachine modeling. The main application is the simulation of off-design regimes and unstable situations (essentially surge). Two specific approaches are developed: the first is a simple and fast model, based on a simplification of actuator disk model (0D).

Facing the Challenges in CFD Modelling of Multistage Axial Compressors
Volume 2B: Turbomachinery, 2017Multistage axial compressors have always been a great challenge for designers since the flow within these kind of machines, subjected to severe diffusion, is usually characterized by complex and widely developed 3D structures, especially next to the endwalls. The development of reliable numerical tools capable of providing an accurate prediction of the

Optimization of a Multistage Axial Compressor Stochastic Approach
Volume 1: Turbomachinery, 1992A procedure of a multistage axial compressor (MAC) parameters optimization in stochastic setting has been offered. The procedure allows to obtain a stable solution from the point of view of its practical realization. A concept of robustness (stability) of turbomachine optimum design has been introduced, and the criteria of stability degree evaluation ...
