The Interaction of the Wake from an Oscillating Blade with a Fixed Cascade
Published online by Cambridge University Press: 07 June 2016
Summary
The paper presents a theoretical investigation of the flow when the wake from a single vibrating aerofoil interacts with a fixed downstream cascade set normal to the mean flow direction. It is concluded that the effects of the cascade extend upstream by a distance of about one quarter of the wavelength of the fluctuations in the wake. It is also found that the wake passes through the cascade unchanged in strength, but that the cascade sheds vorticity of equal and opposite magnitude, so that, if an average is taken in the direction parallel to the cascade, the wake is annulled.
