AUSPLUME is an air pollution dispersion modelling system developed by the Environment Protection Authority of Victoria (Australia) for air quality management. This paper describes the mathematical formulation of a skewed probability density function (PDF) module included in AUSPLUME to predict daytime convective mixing of plumes from tall stacks. The values of the six turbulence parameters used as input in the PDF module are determined and the stand-alone module is compared with data from laboratory and field experiments. The paper also prescribes meteorological conditions under which the PDF model should be used, as well as plume-rise formulae and the lateral diffusion coefficient. The modified AUSPLUME code is tested for consistency using the ideal condition parameters that are used in the development of the original stand-alone PDF module. [ABSTRACT FROM AUTHOR] |
