In the Spring of 2010, a series of field trials were performed at Dugway Proving Grounds, to investigate the release behavior of large-scale releases of toxic industrial chemicals (chlorine and ammonia) stored under liquefied gas conditions. The FLACS CFD tool was used as part of a study sponsored by the DHS Chemical Analysis Security Center (CSAC) to investigate the behavior of the flashing jet released from the storage tank and impinging onto the ground. In addition to the near-field behavior of the two-phase flashing jet, the CFD simulations modeled the resulting vapor cloud as it dispersed downwind. This paper will present the CFD simulation results of the downwind dispersion of the vapor cloud and compare them to the experimental data. The comparison will focus on data from the chlorine trials.
