A particle image velocimetry technique was used to study fluid flow around two identical circular cylinders arranged side-by-side with a fixed center-to-center distance. The vertical location of the cylinder pair was varied. The cylinders spanned the tunnel test-section and were oriented normal to the streamwise direction. The Reynolds number based on the cylinder diameter and the approach velocity was 2030. The mean velocity, turbulence intensities, Reynolds shear stress, and momentum flux distributions are used to study the influence on the flow of the free surface at the top of the tunnel and the wall at the bottom of the tunnel.
