Figure 3 - Large scale PIV applied to flow interaction downstream a semi-open barrier

a-c) Time sequence of 3-second averaged flow velocity. A large vortex (indicated with the yellow arrow) is shed from the upper pillar. Smaller structures are present in the flow downstream the HATTs (in the middle).
