Abstract
The addition of freestream disturbances is carried out at Reynolds numbers approaching full scale. These data, in the form of surface pressures collected on the front face and beneath the separation bubble, suggest that the mechanism of peak pressures does not solely come from the amplitude of a single length scale as some have suggested. Rather, the peak events are simultaneous fluctuations of several length scales. This finding is subsequently discussed as it contains consequences for those modeling in wind tunnel environments or those who are unable recreate the natural wind spectrum in its entirety.
