The Development of a Multistage Axial Compressor Research Facility
47th AIAA/ASME/SAE/ASEE Joint Propulsion Conference & Exhibit, 2011Recent renovations to the Purdue 3-stage axial compressor research facility have led to improved inlet flow to the facility and expanded driveline capabilities. The original layout included a front-driven compressor, which led to challenges with uniformity of inlet air temperature and velocity profiles.

Full annulus simulation on a multistage axial-centrifugal combined compressor
Proceedings of Global Power & Propulsion Society, 2023Axial-centrifugal combined compressors are widely used in small and medium aero-engines. This study aims to investigate the performance and flow characteristics of a multistage axial-centrifugal compressor using annulus unsteady simulation. The compressor comprises three axial stages and one radial stage, including the inlet and outlet guide vanes. 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 ...

Multistage Axial Compressor Flow Field Predictions Using CFD and Through-Flow Calculations
Volume 2C: Turbomachinery, 2016A comparison between two different methods for aerodynamic calculation of multistage axial compressors is presented. Results obtained using classical 2D through-flow calculations were compared with CFD results for several test cases, including various subsonic and supersonic multistage axial compressors with different geometric configurations and stage

Attenuation of circumferential inlet distortion in multistage axial compressors.
Journal of Aircraft, 1968Circumferential inlet distortion in a high hub-tip ratio multistage machine is treated by analyzing the compressor as a region in which a large number of small stages produce a pressure rise that is a function of the local mass flow rate. The resistance to circumferential flow due to the blading is included through an empirical factor. It is found that

Numerical Simulation of Particulates in Multi-Stage Axial Compressors
Volume 2A: Turbomachinery, 2016Aircraft engines ingest airborne particulate matter, such as sand, dirt, and volcanic ash, into their core. The ingested particulate is transported by the secondary flow circuits via compressor bleeds to the high pressure turbine and may deposit resulting in turbine fouling and loss of cooling effectiveness.

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

Dynamic simulations of post-stall performance in multistage axial compressors
Journal of Thermal Science, 2012In this contribution a quasi-one-dimensional tool for stationary and transient simulations of post-stall flows in multistage axial compressors is presented. An adapted version of the 1D Euler equations with additional source terms is discretized with a finite volume method and solved in time by a fourth-order Runge-Kutta scheme.

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).

Unsteady Flow Effects in a High-Speed Multistage Axial Compressor
Volume 7: Turbomachinery, Parts A and B, 2009As a first step in practical application of virtual rig test, in present work, a full unsteady multistage simulation was performed for a 6-stage transonic axial compressor at design point. A steady multistage simulation was also performed and compared with the results of the unsteady simulation to clarify the unsteady flow effects.
