These novel structures reduce or may eliminate the amplification of pressure drops caused by wind gusts flowing over the rooftop. By focusing on understanding the vortex behavior as it is connected to rooftop suctions, the unusual corresponding pressure characteristics may be more fully examined. 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. N. (June 1999) “A model of roof-top surface pressure dependence upon local flow parameters,” Wind Engineering into the 21st Century, 1097-1104, and presented during proceedings of the 10th International Conference on Wind Engineering, in Copenhagen. FIGS. 2A and 2B are isometric depictions of the vortices that forms atop the roof (FIG. “Reattachment” of the flow is defined to occur at the ‘end’ of the separation region and is the point/area at which the flow returns to traveling generally parallel to the roof surface, once again, easier seen in FIG.

Ideally, the preferred structures of an apparatus of the invention are positioned and affixed to disrupt, or, ‘catch’/separate, the flow within the on coming flow’s transition region (TR) such that this point of reattachment (e.g., 29) is moved further out and away from the roof-wall edge, toward the right in FIG. 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. Permanent affixation or mounting-to the extent a ‘permanent’ mode is possible, given inclement weather and expected harsh and routine outdoor conditions-of the structures to a rooftop, wall, ground support, and so on, can be accomplished by employing a suitable mechanism selected from a wide range of those available, as well as specifically-tailored designs, including bolts, screws, wiring, fastening plates, weather resistant adhesive, with or without press fit engagement, partially or fully embedding or otherwise integrating a support member of the structure within the roof, wall, or ground extension by molding, forming, setting, press-fitting, and so on; or any combination of the above.
Although not illustrated, one can appreciate that the support may be anchored to any of these. 7A and 7B and shown but not labeled for simplicity in the remaining FIGS. 4A, and cornering wind, traveling in the direction of arrows 112 as shown in FIG. Dolor lumbar sentado . FIG. 3A is a two-dimensional depiction of the vortex flow model illustrating a snapshot of a vortex outlined at 27, and placement of an apparatus of the invention having a leading edge portion with a leading-rim extending into the oncoming flow’s transition region (TR) such that, here, it protrudes out over the edge a horizontal distance labeled “d” for reference. 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. This unstable re-circulation region can include a vortex such as those depicted with swirling arrows throughout the drawings-necessarily in depicting such wind phenomena in still-life schematic views, an instant in time is captured and drawn although in the case of wind gusts, vortices existing within the re-circulation region are quite unstable.
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. 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. For further reference, in connection with the theoretical framework for flow characterization of incident wind, see Attachment A, Banks, D. (spring 2000), and Attachment B, Wu, F., excerpts from dissertation, Chapter 8-both of which are identified above and are incorporated herein be reference.

A second elongated member can be joined at an end of the first elongated member in angled positional relationship, such as is shown in FIG. Although shown to extend along each edge-length and each corner of rooftop 110, according to the invention, shorter edge-lengths/sections of the elongated structures may be used ‘locally’-for example, along a corner in an open-V (for reference, FIG. 3A except no apparatus of the invention is shown for simplicity.

The cross-section of the elongated member, taken between the leading edge portion and trailing end portion of the elongated member, can be of a number of identifiable shapes such as: an oval, a thin-irregular oval, an airfoil, a triangle, a rectangle, a thin-irregular rectangle, a circle, a thin-plate having a curvilinear leading edge portion, a thin-irregular wave-shape, a polygon, and a thin-irregular polygon, for reference by way of example only, see FIGS. 6 at 60A and 60B and in FIGS. These drawings and materials have been included to communicate features of the innovative apparatus of the invention by way of example, only, and are in no way intended to unduly limit the disclosure hereof. Dolor de hombro izquierdo significado emocional . Briefly described, once again, the invention includes an apparatus secured to extend upwardly from a rooftop for redirecting free oncoming flow of a gas passing over an edge of the rooftop. FIGS. 7A-7F are sectional views of alternative structural configurations for an apparatus of the invention atop a side plan view of the building rooftop.
