Temporally and spatially resolved flow in a two-stage axial compressor. Part 2: Computational assessment [PDF]
Fluid dynamics of turbomachines are complicated due to aerodynamic interactions between rotors and stators. It is necessary to understand the aerodynamics associated with these interactions in order to design turbomachines that are both light and compact

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.

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

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.
