EXPERIMENTAL INVESTIGATION OF FLOW STRUCTURE DOWNSTREAM OF PERMEABLE CYLINDERS

Abstract

Flow
structure downstream of permeable cylinders was investigated using high-image
density Particle Image Velocimetry technique in deep water. The free stream
velocity is U= 156 mm/s, which corresponds to the Reynolds number
of Re=6250 based on the cylinder diameter D=37.5 mm. To reveal the effect of
the porosity, four different porosities (β= 0.4, 0.5, 0.6 and 0.7) were used.
This study showed that the usage of permeable cylinder decreases the occurrence
of large-scale vortical structures downstream of the bluff body. As the
porosity increases, turbulent kinetic energy, Reynolds shear stress and
intensity of turbulences decrease as a sign of attenuated fluctuations in the
wake region. For the permeable cylinders having the porosity higher than 0.6,
the flow behaves as there is no object in flow.
