Abstract
This experimental work is the result of a collaboration between the Mechanical
Engineering Department of Cagliari, Italy, and the von Karman Institute for Fluid
Dynamics, Brussels. Here the flow field downstream of a backward facing step in
a low speed wind tunnel was experimentally studied by means of a PIV system,
and series of images of the instantaneous flow were acquired and averaged to
obtain the mean flow field and turbulence information. The same flow region in
similarity conditions was experimentally investigated by an optic fibre LDV
system, in a similar test facility in Cagliari university.
The averaged flow field is characterised by a principal recirculation region
downstream of the step, together with a secondary vortex locate
