A sesquilinear model analysis for pollutant dispersion by the Copenhagen experiment

Abstract

Dispersion of chemical agents in the atmosphere is a physical phenomenon influenced by micrometeorological variables that directly alter the dispersion behavior. The objective of a mathematical model is to aggregate information to the governing equations so that simulations reproduce a good approximation of the phenomenon. Measurements obtained through experiments help to calibrate and analyze the results obtained by mathematical models. The analytical model presented here is based on the advection-diffusion equation using Fick’s closure, whereas the concentration field is a result of a sesquilinear representation. The Copenhagen experiment was used to identify a systematics of the model parameter set with the atmospheric stability regime of the experiment.
