Wind loads on photovoltaic arrays mounted parallel to sloped roofs on low-rise buildings
TL;DR: In this paper, the effects of geometry on the wind loads acting on photovoltaic panel arrays with modules mounted parallel to the roof surfaces of low-rise buildings were investigated, and it was found that larger gaps between modules, G, and smaller gaps between the panels and the roof surface, H, were found to yield lower net wind loads.

Wind loads on residential scale rooftop photovoltaic panels
TL;DR: In this article, large-scale models of rooftop photovoltaic (PV) panel arrays on residential buildings were tested in the Wall of Wind Research Facility and the results revealed that the critical wind directions that induced the worst maximum and minimum peak force coefficients were depended on roof type and panel tilt angle.

On errors of digital particle image velocimetry
TL;DR: In this article, a peak-normalization method was introduced to make the mean bias error negligible in comparison with the root-mean-square (RMS) error, and a peak compensation technique was also introduced to reduce the RMS error.

Long-Duration Time-Resolved PIV to Study Unsteady Aerodynamics
TL;DR: The buildup of flutter is shown to exhibit complex dynamics that are heavily influenced by the flow-induced motion of the body, and features of the wake turbulence as a function of time are presented and shown to substantially vary.
