| Resumen |
Data from 26 dense gas field experiments are compared with physical model simulations. In general the model clouds are very similar in appearance, they spread and travel at correct rates, measured concentrations compare very well, and peak concentrations are often predicted to within a factor of two or better. Model simulations where specific gravity, volume flux ratio and Froude number equality are maintained produce the most successful predictions of field concentrations. When only volume flux ratio and flux Froude number equality are stipulated, peak concentration isopleths are preserved, but the time of arrival and departure of the dense clouds is distorted. Field/fluid model comparisons reveal that lower flammability distances for liquefied natural gas or propane spills are predicted within a standard deviation of 25% with a 90% level of confidence. |
