Peak wind loads under delta wing vortices on canopy roofs

Pressure contour plots on pitched canopy roofs indicate that the largest pressures are experienced close to the leading edges and the ridge line at a wind orientation of ∼ 30°. Surface flow patterns and pressure contour plots identify the flow mechanisms causing these large pressures as flow separation and the formation of conical delta wing vortices. The correlation between fluctuating surface pressures is increased under the delta wing vortex. An eigenvalue analysis shows that the mechanisms contributing most to the large fluctuating pressures close to the leading edges are flow separation and delta wing vortex formation. Area averaged pressures close to the leading edges and the ridge line are substantially greater than the pressures on the rest of the roof. © 1992.
