Effect of Face Velocity and the Nature of Aerosol on the Collection of Submicrometer Particles by Electrostatic Precipitator
Morawska, Lidia, Agranovski, Victoria, Ristovski, Zoran, & Jamriska, Milan (2002) Effect of Face Velocity and the Nature of Aerosol on the Collection of Submicrometer Particles by Electrostatic Precipitator. Indoor Air, 12(2), pp. 129-137.
Despite the electrostatic collection of aerosol particles is one of the most widely used air cleaning methods, there have not been sufficient amount of effort devoted to investigate its performance in the full range of operating conditions. This paper reports results of the tests of a two-stage electrostatic precipitator (ESP) conducted in the particle size range of 0.018 - 1.2m over a range of flow rates using NaCl and Environmental Tobacco Smoke (ETS) test aerosols. The total collection efficiency of the precipitator was found to increase with an increase in the count median diameter (CMD) of the particles, to have polynomial dependence on flow rate and no significant dependence on the type of test aerosol. The fractional efficiency of the precipitator was found to be dependent on flow rate. However, the “critical” particle size of about 1.2 m was found to exist when the fractional collection efficiency becomes independent of flow rate. For submicrometer particles, the collection efficiency was found to be independent of particle size at flow rates below 560 L.s-1. A minimum in the efficiency was observed in the 0.1 to 0.45 m particle size range and for particles smaller than about 0.02 m.
Citation countsare sourced monthly fromand citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloadsdisplays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
