Clearing of Military Smoke Cloud with Scavenging Technique
Abstract
A survey of parameters describing the settling of nonspherical scavengers such as disks, hexagons, triangles, ellipses, squares, rectangles, and mesh type models for setting in quiescent air and at a side wind has been obtained. The experiments with disks exposed to smoke particle flow in a wind tunnel showed that particle deposition on the rear side of a collector represents a significant part of the total scavenging effect and that the deposition on the front side of a stationary disk can be reasonably well described by some of the existing models. The estimated scavenging efficiency of the disks in this arrangement is between 0.8% and 3.0%. Under the experimental conditions used, dropping of a large quantity of paper punch scavengers into a smoke cloud might lead to the improvement of a visual range up to 29% after the first dropping and up to 9% after each of the subsequent droppings.
