DISPLAY-2: a two-dimensional shallow layer model for dense gas dispersion including complex features

The Viareggio LPG railway accident: Event reconstruction and modeling

“…This phenomenon is modeled only by DISPLAY-2 [22]. In addition, since there were rather calm weather conditions (see Table 2), the motion of the gas cloud by the wind was negligible respect to the gravity slumping.…”

Influence of wind speed profile and roughness parameters on the downwind extension of vulnerable zones during dispersion of toxic dense gases

“…Atmospheric dispersion modelling of dense gases (Ermark & Chan, 1985;Hildermann, Hrudey, & Wilson, 1999;Van Ulden, 1983;Venetsanos, Bartzis, Wurtz, & Papailiou, 2003) and estimation of downwind extension of vulnerable zones due to accidental release of toxic chemicals in an industry form an integral part in framing an emergency management plan for that industrial estate. In industrial estate, various types of toxic, flammable and explosive chemicals are stored and used in the process.…”

Validation of turbulence models in heavy gas dispersion over obstacles

“…In this paper, k-ε in addition to three other newly developed turbulence models (k-ω, shear stress transport and SSG Reynolds) are tested against Thorney Island field trials data. Thorney Island experiments are well documented and analyzed in depth in the relevant bibliography [6][7][8] providing useful information for subsequent dense gas experiments set-up [9] and constituting a reliable data set that have been used in verification procedures of box [10] or more complicated [11][12][13][14] dispersion models.…”
