FIG. 1A is an isometric depiction of the vortices that form atop a building structure having a rooftop 10, due to a cornering wind. 3A, 5B, 7A-7F, 9, 10, 12A-12D. Thus, as shown, the upper and lower flow-surfaces may each be generally planar, may include one or more curvilinear surface (convex or concave), may include an angle, and so on. 3A, one or more curvilinear surface, e.g., FIG.
In FIG. 9, member 150 has a cross-section the shape of a thin oval having a leading edge portion with a curvilinear surface and is oriented at an incline with respect to rooftop 110 as supported by support 158. FIG. 1B, illustrating oncoming free flow 22, separated here by the addition of an elongated member 20A of the invention, cross-section is shown, here-see also FIGS.

More particularly, the invention relates to unique rooftop structures and method for mitigating wind suction using an associated novel structural protuberance that extends at least partially into the shear layer/transition layer of the flow, whether permanently fixed to the roof top by suitable means, partially or fully embedding or otherwise integrating within the roof by molding, forming, setting, etc. Critically, in effect, the leading edge portion of the elongated member ‘catches’ at least a portion of the oncoming flow so that it can be redirected under and along the lower flow-surface toward and into the re-circulation region; by doing so, the creation of vortices can be prevented, thus, mitigating the strong suction associated with vortices, atop the roof. Over the rooftop the transition region of the oncoming flow, labeled “TR” for reference in FIGS. 1B, oncoming free flow 22 is separated by the elongated member 20A having a leading edge portion that catches a portion of oncoming flow 22 to redirect (arrows 26) into and toward the vortex depicted at 27. See also FIGS.

8B: Oncoming flow re-circulates to create vortices with strong, structural-damaging suction underneath; for further reference see FIGS. Further, as identified at 220 in FIGS. For reference as suggested, distance, d, can preferably be between 0.05% and 75% of the width, w, of the elongated member as measured from its leading-rim 42 to its trailing end identified generally at 44 of member 40. And further, in terms of spacing, s: distance, d, as shown is less than a vertical distance, s, between the rooftop and a closest point of the lower flow-surface to the rooftop. 25° on either side of the central direction represented by arrow 12. As mentioned above, for incident winds directed generally normal, or perpendicular, to a wall of the building with no significant cornering component-i.e., those incident winds directed toward wall 11B over a range, in FIG.

FIGS. 3A and 3B, for reference, provides a graphical representation, including a snapshot of a vortex outlined at 27, of the terms used in the flow model equations identified, earlier, by at least one of the applicants as discussed in earlier work: Banks, D., and Meroncy R.

Dolor lumbar irradiado a abdomen . 12A-12D: The elongated member has a first lowered position, which, for certain configurations, may mean at least a portion of its lower flow-surface is in contact with the rooftop, and includes moving parts such that it is adapted for moving into a second position. While certain representative embodiments and details have been shown merely for the purpose of illustrating the invention, those skilled in the art will readily appreciate that various modifications may be made without departing from the novel teachings or scope of this invention.

More recent studies indicate that the worst mean and peak suctions on flat building roofs occur for ‘cornering’ or ‘oblique’ wind angles which are those wind components directed toward any corner of the building where roof-wall junction is ‘sharp’, i.e., incident winds directed over a range, in FIG. FIGS. 1A-1B depict the cornering incident wind directed at corner 18 interposed between incident-wind roof edges 15A, 15B along the direction labeled by arrows 12, i.e., incident winds directed over a range labeled 14A, 14B with a representative angle, λ1, from approx.

Once again, at least a portion of oncoming flow 22 is caught by leading edge portion 42 to redirect flow along 26 and into 28, the re-circulation region including, here at this moment in time, a vortex depicted at 27 centering around point O. Arrows labeled 24 illustrate the generally streamlined nature of flow 22 as bounded by 23 within which re-circulation region 28 falls.
Preferably, the elongated member of the invention is mounted/secured/integrated such that its leading-rim extends into at least this transition flow region of the oncoming flow; in most instances, the leading-rim will protrude out over the edge of the rooftop. 10 illustrates a further embodiment of the invention at 160 having a fence-type elongated member and associated support 168 mounted to inclined rooftop 110. The leading edge portion generally shown at 162 preferably extends, as positioned, into the TR such that flow is caught and separated as depicted here. 3A and 3B, is generally bounded, below, by a re-circulation region wherein flow of the wind travels in a circuitous motion. 1C at 29. As one can see, in the normal incident wind case, the separation region encompasses the vortices as well as an area surrounding the vortices. In the normal wind condition, the region of slow or re-circulating flow under the transition or shear layer is called the separation region, or, separation bubble.
