A CORRELATION OF FIELD OBSERVATIONS OF PLUME RISE,

Abstract

Data from 137 sets of plume observations, comprising nearly 1500 data points, are correlated with two simple formulae. These formulae, one for the buoyancy-dominated rise region and the other for the stratification-dominated leveled-off region of a plume, represent an approximate form of an entrainment theory for the case of uniform atmospheric stratification and zero wind shear. The two formulae are found to correlate the data equally well over all values of the stack exit and meteorological parameters, provided only that the bulk mean velocity of the stack gases exceeds the mean wind speed by at least 20%. The ratio of observed to calculated plume rise is found to be distributed log normally about the mean value. (Author)
