Advances in Dense Gas Dispersion Modeling of Accidental Releases Over RoughSurfaces during Stable Conditions

摘要

A major, cooperative research project will be completed in 1997 from which animproved understanding will be gained about the dispersion of accidental, dense gas releases at industrial sites (i.e., high surface roughness) during low-wind stable meteorological conditions. As the wind tunnel experiments are now largely complete, an overview of these experiments is given. Also, some preliminary results from the completed neutral wind tunnel tests are provided, such as entrainment rate as a function of the plume Richardson number. The main field experiment known as 'Kit Fox' was completed during the summer of 1995. A description of these experiments as well as a summmary of the data collected are presented.
