Axial Flow Compressors

The mechanism of mixing in axial flow compressors has been investigated in two low speed machines. For reasons of length this is described in two parts. Results in a 4-stage compressor are described here in Part I and show that the mixing coefficients across the first and the third stators are of similar magnitude. Part I also describes the background and experimental facilities and techniques used in both parts together with the nomenclature and all the references. Part II describes the results from a large single stage compressor. It also presents measurements of mixing in a simple two-dimensional duct, and presents conclusions for the whole investigation.

Axial Flow Compressors

A theoretical model is proposed for the spanwise mixing caused by periodic incoming wakes in the context of turbulent diffusion in axial-flow compressors prior to repeating-stage conditions. The model was used to predict the spanwise mixing coefficients across a stator of a single-stage compressor without IGVs. The correctness of the theory was demonstrated by the results that the predicted values were in good agreement with the associated experimental data.

Despite major advances in axial compressor theory and practice, the lack of a rational method of predicting surge limits remains as an outstanding deficiency. Accumulating experience suggests the association of surge initiation with local stalling phenomena, within the compressor, which are inadequately represented by conventional assumptions. A simple, revised model of stage matching under local stalling conditions is shown to provide a rational and consistent qualitative description of observed compressor off-design and surge initiation characteristics, and the effects on these of a variety of factors. Improved local stall criteria could provide the key to quantitative predictions of multi-stage compressor surge limits.

One of the factors that has to be considered when planning the installation of a turbocharger or gas turbine is the amount of noise that is likely to be radiated from the intake. Frequently such plant employs axial flow compressors, either single-or multi-stage. The object of this paper is to describe how noise is generated in that type of compressor.
