Dense Gas Dispersion in Complex Settings: Part 2 — The Effect of Topography

Part of the book series: NATO ASI Series ((NSSE,volume 277))

Abstract

Variations in the elevation of the underlying surface will influence the buoyancy driven motion of a dense gas cloud. Topography, in the form of general slope, isolated hills, or more complex terrain, will alter or divert the cloud or plume. The topography may enhance plume dilution and divert the plume away from regions of elevated terrain. Alternatively, the dense plume may be channelled into valleys or low-lying areas and then be protected from the diluting influence of the ambient flow. This paper addresses some of the fluid mechanics of the atmospheric dispersion of dense gases, particularly those related to the development of techniques for incorporating the important effects of topography in dense gas dispersion models.
