PIV measurements of the Flow behind a 2D fence in an atmospheric boundary layer wind tunnel
conference paper
High-speed stereo-PIV measurements were performed in the wake of 2.3 m wide fences (respectively 5 and 10 cm high). Average velocities and turbulent kinetic energy levels are given for a near fenceand a downstream field of view, showing the large recirculation zone of a near-2D obstacle. The
results indicate that although PIV measurements can provide a good description of the turbulent flow around a wall-mounted fence, the lateral (perpendicular to the FOV) turbulence levels of the approach flow with roughness length of 0.3 mm are overestimated when compared to hot-wire measurements.
