Unsteady separated-flow dynamics over a box-girder section under sinusoidal inflow: Effects of angle of attack and Keulegan–Carpenter number

The aerodynamic behavior of bluff bridge-deck sections in unsteady inflow depends on both the angle of attack and the time scale of the imposed velocity fluctuation. Active-control wind tunnel measurements and two-dimensional unsteady Reynolds-averaged Navier–Stokes simulations are used to examine surface pressure, aer...
