“…Such work was used to investigate the effects of obstacles, such as the storage tanks themselves (land), or the ship (sea), on the dispersion process. The results were in qualitative agreement with the findings of the Thorney Island trials, see, for example [6], or the later Falcon trial series [7]. However, it is acknowledged that there are many scaling issues related to the use of wind-tunnels (and water-flumes) and, in general, information from such small-scale studies should be regarded as indicative rather than definitive.…”

“…The complete structure was mounted on a trailer and was moved to the required position shortly before the release of gas, according to the wind direction record. The gas source was a cylindrical (actually 12-sided) tent of 14 m diameter, 13 m height and total volume capacity of 2000 m 3 , made from flexible material, which was left to fall to the ground at the beginning of each trial [20].…”

“…For the validation of the heavy gas turbulent dispersion model, we have selected field experiments based on the Thorney Island Trials studies, [25][26][27]. The Thorney Island Trials experiments addressed the temporal evolution of heavy gas cloud under various wind conditions.…”

In the present study, we focus on modeling and simulations of macroscopic behavior of a crowd of people under emergency conditions. We present a newly developed integrated numerical approach, which combines the time-dependent RANS method in predicting the temporal and spatial evolution of a heavy gas turbulent dispersion with the macroscopic model of a crowd movement. The coupling is imposed through locally determined concentration of the heavy gas which directly impacts the movement of the crowd of people. The potential of the developed approach is demonstrated in a series of cases that include the crowd behavior on an open railway platform and inside a train station, as well as predictions of field studies of turbulent dispersion of a heavy gas under windy conditions. Finally, various scenarios have been analyzed of the coupling between the local concentration of a potentially harmful heavy gas on crowd behavior through different forms of the cost functions. In conclusion, the version of the integrated model is recommended for future optimization studies of crowd dynamics following an incidental release of heavy gas.
