Title: A new model for estimating concentrations of substances emitted from a line source

Abstract

Gaussian models, which are generally used to evaluate concentrations of airborne materials originating from an infinite line source, have usually been based on the incorrect assumption that the vertical dispersion constant is nearly independent of the time required for the substance to go from source to receptor. A new model based on the theory that the vertical dispersion constant is some type of time function is examined. The new model, which is applicable to all receptor heights and distances, to all wind speeds, and to all wind directions, predicts that concentrations of a substance at a remote receptor will be independent of wind speed. The model's reliability was verified with data comparisons from General Motors Co. performance tests. (1 graph, 11 references, 2 tables)
