Wind Tunnel and Numerical Modeling of Atmospheric Boundary Layer Flow Over Bolund Island

The paper presents a comparison between the experimental and numerical results on the flow around a Bolund Island 1:705 scale model. A boundary layer wind tunnel with expansion stage was used for experimental modelling [9]. Velocity fields were determined using Constant Temperature Anemometry (CTA) and Particle image Velocimetry (PIV) measurements. Unsteady numerical simulations were performed using a Reynolds Average Navier Stokes (RANS) turbulence model adapted to atmospheric boundary layer flows [6] which was implemented in the ANSYS FLUENT expert software.
