摘要

The purpose of the work discussed here was to study the nature and extent of the disturbance to the dispersion process when a dense gas cloud originating from an instantaneous release and dispersing over level ground is obstructed by a fence. This information is needed to extend the scope of the HSE risk assessment tool RISKAT to allow for the effects of methods of containment such as bunds and of pre-existing obstacles such as rows of buildings. Evidence is produced for a power-law relationship between the reduction in cloud concentration attributable to the presence of a solid fence and the fence height.
