Interaction of Upstream Flow Distortions With High Number Cascades
Keyword(s):
This analytical study models features of the interaction of flow distortions, such as gusts and wakes, with blade rows of advance type fans and compressors having high tip Mach numbers. A typical disturbance is described, at afar upstream location, in three orthogonal spatial coordinates by a double Fourier series. It is convected at supersonic velocity relative to a linear cascade described as an unrolled annulus. Details of interaction of the disturbance with an in-passage shock are discussed. Influences of amplitude, wave length, and phase of the disturbance on lifts and moments of cascade configurations are presented.
