Comparison of ADORA and other models with experimental observations for a spill of anhydrous hydrogen fluoride.
Under normal conditions, HF is heavier than air. When HF stored under normal ambient conditions is released into the atmosphere, it slumps to the ground. Subsequently, HF disperses
as a ground-based cloud. A spill of HF was modeled by ADORA and the other models. In this figure the calculations are compared with the experimentally measured cloud
concentrations. Again, the ADORA predictions match the experimental results very closely. For this case, the experimental concentrations are higher than SLAB and DEGADIS and much
lower than HGSYSTEM predictions.
