Study on the mathematical model for the buoyant plume rise (1)

buoyant plume trajectory

Abstract

This paper presents techniques for determining the mean trajectory of plume emitted from a stack. Equations presented are not intended to provide a means for predicting day-to-day variations in plume trajectory for a given stack.
This investigation has been analyzed on the basis of the theory that there is a non-linear relation between plume rise and distance downwind on the Log-Log graph, not on the traditional linear relation “2/3 Power-Law.”
The equations for predicting plume trajectory are developed statistically and give good agreement with many field data which were observed not only in Japan, but in U.S.A. and Europe.
