A Methodology for Variable Geometry Optimization of Multistage Axial Compressors

Volume 2A: Turbomachinery, 2017
This paper presents a procedure for experimentally optimizing a multistage axial compressor. Due to the usual proprietary nature of such tests, a mean-line model of a nine-stage compressor with three rows of variable geometry is used instead of a real machine as a testbed for explaining the optimization method.

Multistage Axial Compressor Program on Tip Clearance Effects.

1981
Abstract : Tip clearance has long been known to be a source of losses in axial compressors with cantilevered blades. The reasons for the losses, however, are not well understood and current practice in engine design still requires extensive effort to maintain constant minimal operating clearances over a wide range of conditions.

Efficient Time Resolved Multistage CFD Analysis Applied to Axial Compressors

Volume 2D: Turbomachinery, 2014
Unsteady computations are necessary if blade row interactions effects are relevant, for example for detailed optimization of a compressor at off-design conditions towards the aerodynamic stability limit, or for structural mechanical tuning of the blades.

A New Multistage Axial Compressor Designed With the APNASA Multistage CFD Code: Part 2 — Application to a New Compressor Design

Volume 1: Aircraft Engine; Marine; Turbomachinery; Microturbines and Small Turbomachinery, 2001
In this second part of a two-part paper on the application of the NASA multistage aerodynamic simulation CFD tool, the APNASA code, work is presented on how the code was used successfully in the design of a brand new, four-stage axial compressor aimed for a modern turbofan engine.
