Response Analysis of Cooling Tower Plume Dispersion to the Release Height

Abstract

The SACTI model (Seasonal Annual Cooling Tower Impact) as the environmental impact assessment of cooling tower was applied in this paper, which was used to simulate the plume characters under different cooling tower heights. The results showed that the plume length, plume height and plume radius presented noticeable differences with variances of different distances and wind directions under different cooling tower heights. The comparisons of differences of plume characters indicated that the relative change of plume length frequency displayed obvious decreased trend with increased distance when distance was greater than 500m, and that of plume height frequency appeared parabolic curve with increased distance. The relative change of plume radius frequency expressed totally descended trend.
