Investigation of a Complex Technique of Smoke Particle Deposition on Scavengers
Abstract
Numerical models were applied for assessing the smoke particle scavengers of simple geometry. The results were compared with the experiments in laboratory wind tunnels and in a smoke chamber, where light extinction measurements were performed in a TiC14 cloud. Most effective scavengers were mesh type collectors and filter type material consisting of electrete fibers. Their maximum collection efficiency surpassed 10% for collectors bearing no additional electrical charges. The effect of this scavenging technique can be increased by appropriate combination of different types of fibers with respect to the specific (anticipated) aerosol size distribution. For some of the selected types of scavengers the dispersion cone has been deduced experimentally and the behavior and aerodynamic interactions of falling scavengers described in calm air. Keywords: Scavening military, Smoke particles, Evolution falling, Scavenger, Zones, Aerodynamic, Interaction.
