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

maximum plume rise

Abstract

This paper deals with techniques for estimating maximum rise of the bent-over plume. Information on plume rise is important in determining the concentrations of pollutant on the ground. Practical use of plume rise values may be made in connection with stack design, the use of urban air pollution mod ls, and in evaluating the hazards to a population complex.
This investigation is made on the objective assumption that the plume is levelled off when its vertical velocity is below 0.1 m/sec so that it can yield levelled-off point (x_max) and maximum plume rise (ΔH_max). The empirical formulas for estimating maximum plume rise are derived by multiple regression analysis and give good agreement with many field data.
