Heavy Gas Dispersion Test Summary Report

Abstract

This report summarizes the results from selected field-scale, heavy gas dispersion test, which can be used to validate atmospheric dispersion models. A total of 26 benchmark tests were chosen from the Lawrence Livermore National Laboratory Burro (LNG), Coyote (LNG), Desert Tortoise (ammonia), and Eagle (nitrogen tetroxide) tests; the Shell Research Ltd. Maplin Sands tests (LNG and LPG); and the British Health and Safety Executive Thorney Island test (freon-air mixtures). Only continuous finite duration releases were selected for the test summaries as they were considered to better represent typical accidental releases from a storage vessel or transportation vehicle. The test summaries describe the manner of release, the ambient meteorological conditions, and the resulting vapor cloud characteristics including peak concentration, average centerline concentration, and average height and width of the cloud, all as functions of downwind distance. Keywords: Model validation; Model evaluation; Diffusion model; Hazard response model; Air pollution. Heavy gases.
