FLACS (flame acceleration simulator) is established as a very powerful CFD (computational fluid dynamics) tool for gas dispersion, in particular for situations where detailed description of geometry details is of importance (process facilities, urban areas and more). Numerous validation activities have been carried out in the past, the current paper describes a validation activity simulating the dispersion from LNG-release experiments Burro, Coyote and Maplin Sands. Results are generally good, FLACS predicts downwind natural gas concentrations with reasonable precision assuming the released LNG quickly evaporates from a pool with boiling point temperature. A further improvement of pool models is described in the paper which hopefully will lead to a more realistic description of accident scenarios simulated in connection to risk assessments.
