Wind-tunnel research on the mechanics of plumes in the atmospheric surface layer
Abstract
The diffusion of a neutrally buoyant gas emitted from point sources into neutral, stable, and unstable boundary layers that simulated atmospheric conditions were studied in a meteorological wind tunnel for flow over two surface roughnesses. Measurements were made of the mean flow velocities and temperatures, turbulence intensities, velocity correlations, and gas concentrations in the diffusing plume. Empirical models were developed for predicting diffusion under all three stabilities studied.
