The WINCOF-I code: Detailed description [PDF]
The performance of an axial-flow fan-compressor unit is basically unsteady when there is ingestion of water along with the gas phase. The gas phase is a mixture of air and water vapor in the case of a bypass fan engine that provides thrust power to an ...

International Journal of Rotating Machinery, 2015 Blade row interactions in turbomachinery can lead to blade vibrations and even high cycle fatigue. Forced response conditions occur when a forcing function (such as impingement of stator wakes) occurs at a frequency that matches the natural frequency of ...

End-wall boundary layer measurements in a two-stage fan [PDF]
Detailed flow measurements made in the casing boundary layer of a two-stage transonic fan are summarized. These measurements were taken at a station upstream of the fan, between all blade rows, and downstream of the last row.

Stalled and stall-free performance of axial-flow compressor stage with three inlet-guide-vane and stator-blade settings [PDF]
The performance of the first stage of a transonic, multistage compressor was mapped over a range of inlet-guide-vane and stator-blade settings. Both stall-free and deep-stall performance data were obtained.

A theory of post-stall transients in multistage axial compression systems [PDF]
A theory is presented for post stall transients in multistage axial compressors. The theory leads to a set of coupled first-order ordinary differential equations capable of describing the growth and possible decay of a rotating-stall cell during a ...

Blade selection for a modern axial-flow compressor [PDF]
The procedures leading to successful design of an axial flow compressor are discussed. The three related approaches to cascade selection are: (1) experimental approach which relies on the use of experimental results from identical cascades to satisfy the

Considerations for High-Fidelity Modeling of Unsteady Flows in a Multistage Axial Compressor
International Journal of Turbomachinery, Propulsion and PowerThis paper presents the development and validation of a high-fidelity, unsteady, computational fluid dynamics (CFD) model of the Purdue 3-Stage Axial Research Compressor. A grid convergence study assesses the spatial discretization accuracy of the single-
