Engineered roughness elements, arrays thereof, and their method of use

摘要

In one embodiment, the present disclosure provides an engineered roughness element. In another embodiment, the present disclosure provides an array of engineered roughness elements. The engineered roughness elements are configured to reduce sand movement and accompanying dust generation.

主权项

1. A method of reducing airborne particles in an area, comprising placing a plurality of engineered roughness elements in or proximate the area in an array, the plurality of engineered roughness elements being spaced apart from one another by at least about 1.7 meters, at least a portion of each of the engineered roughness elements having a height of between about 0.05 meters and about 10 meters, at least a portion of each of the engineered roughness elements having a width of between about 0.05 meters and about 10 meters, at least a portion of each of the engineered roughness elements having a depth of between about 0.05 meters and about 10 meters, each of the engineered roughness elements comprising an upper dust control element coupled to a buse by an arm, the base comprising a bottom portion curved to allow the engineered roughness elements to tilt when the upper dust control element is contacted by wind having a sufficient velocity, and the array configured to provide a reduction in airborne particles of at least about 50% by reducing sand movement in, or proximate to, the array.
