Abstract
An analysis is given, based on rapid distortion theory,
of the effect on homogeneous
turbulence when it passes through a linear cascade of
thin flat plates or aerofoils and
in particular the turbulence that emerges on the downstream
side. The main results are
evaluated for the limiting case in which the spacing ratio
of the cascade is very small
so that the cascade tends to completely suppress the normal
component of velocity of
the turbulence everywhere, both within the cascade and
downstream of it, resulting in
a ‘planar’ (quasi-two-dimensional) turbulence.
Some comparisons with experimental
measurements of grid generated turbulence passed through
cascades of thin aerofoils
and in the regions adjacent to the wakes of isolated
streamwise plates in a wind tunnel are shown.
