We are employing the SLAB model in ongoing studies of the atmospheric dispersion of heavy gases. SLAB computer simulations of four of the Burro series large-scale 40-m³ liquefied natural gas (LNG) spill experiments at China Lake, California have been successful in predicting distances to the lower flammability limit (LFL). We have used this model in simulations of three of the Coyote series of experiments as well as in parameter variation and sensitivity studies and improved simulations of some of the Burro tests. The parameters studied include source rate, wind speed, atmospheric stability, type of source gas, and source duration, as well as the parameters important to certain physics submodels.
