The effect of turbulence in wind tunnel testing of bridges

My PhD is about using an active turbulence grid to study the effect of turbulence on the aerodynamic properties of bridge cross-sections. I utilize wind tunnel testing with a forced vibration rig, an active turbulence grid and various bridge section models to deduce aerodynamic properties in turbulent flow.
