Axial Flow Compressors

1979
The only additional material here over that in chapter 4 is that it is convenient in the velocity diagrams to specify angles δ and γ for trigonometric purposes and polytropic stage efficiency is of importance since axial compressors, which are usually multistage machines are mostly designed on the basis of one stage with an assumed constant stage ...

On the Aerodynamic Design of Axial-Flow Compressors and Turbines

Journal of Applied Mechanics, 1948
Abstract In this paper a theoretical method is presented to determine the flow of a perfect (frictionless, incompressible) fluid across a cascade built up of arbitrary airfoils. The presentation refers to compressor blading but is immediately applicable to turbine blading.

Modified Surge in an Axial Flow Compressor

Volume 1: Turbomachinery, 1992
This paper deals with an experimental study of the unsteady flow in a multistage axial-flow compressor with a high design flow coefficient (p = 1.2) at rpm lower than the design ones. A detailed description of the rotating stall during the so-called “modified surge” is given.

Growth of a Perturbation in an Axial Flow Compressor

Journal of Engineering for Power, 1979
A time-dependent linearized approach is used to predict the amplification or the decay of an initial perturbation in the multistage axial compressor of high hub-to-tip ratio. This analysis shows that for unstalled flow regimes the change in perturbation amplitude remains limited. The linearized theory remains valid until the stall limit.

Unsteady Flow in Axial Flow Compressors

1991
A review is made of the experimental rotating stall work on a low-speed compressor stage. The instantaneous flow field inside the cell is explored using multiple hot wires in the absolute frame of reference. Rotor blade stall and radial drift of the boundary layer is investigated by on-rotor blade instrumentation.

Axial-Flow Compressors for Gas Turbines

Journal of Fluids Engineering, 1948
Abstract The development of the gas turbine during the last decade has opened a new field for compressor application. The compressor is an essential component of every gas-turbine power plant. It delivers air at some elevated pressure to the burner in sufficient quantity to maintain an efficient combustion of fuel and to cool the ...

Unsteady aerodynamics in an axial flow compressor

2001
Current methods for designing compressor blades in axial turbomachines assume that the flow through each blade row is steady. However, interactions associated with the relative motion of neighbouring blade rows are known to produce a disturbance field with both random and periodic components.
