In this two part article in its first part models of heavy gas dispersion in the atmosphere are
classified and the distinguished groups of models are characterised. In the second part the …

An interactive computer model (DEGADIS) which uses a lumped parameter approach to
simulate a wide variety of denser-than-air gas release scenarios, including instantaneous …

A technique for incorporating buoyancy-driven dynamics in a Lagrangian puff model is
described. The dynamic effects are non-linear and therefore proper treatment requires …

Abstract The Heavy Gas Dispersion Trials (HGDT) project consisted of an extensive
programme of field trials on the dispersion of heavy gas clouds at ground level in the …

通过对国内某重大高含硫井喷事故进行调查, 采用大涡模拟方法对3 口井井喷气体扩散进行模拟,
计算不同风速风向在事故中造成的灾难后果, 得出地形因素对于灾难的影响 …

The aim of this paper is to compare theoretical models with the observed behaviour of the
heavy gas clouds in the Phase I Thorney Island field trials for small times after release. The …

The time-dependent behaviour of non-Boussinesq high-Reynolds-number density currents,
released from a lock of height h0 and length x0 into a deep ambient and spreading over …

Once a hazardous gas leaks, it will pose a serious threat to the safety of people's lives and
property. This paper aims to investigate the flow characteristics of heavy gas leakage and …

Unintentional releases of hazardous gases have led to significant injuries and fatalities in
severe cases. Field tests can be used to release hazardous gases to document and …

The spread of a heavy gas cloud in terrain with obstacles has been studied in the wind
tunnel. Observations were made at scales of 1: 100 and 1: 50 using video and photographic …
