Guidelines for fluid modeling of dense gas cloud dispersion

Fluid modeling experiments can predict the behavior of complex dispersion phenomena associated with the dilution of flammable or toxic dense gases after inadvertent release. Such studies are desirable because variables can be controlled at will with great savings in time and expense over full-scale tests. The reliability and value of fluid modeling experiments will depend upon proper applications of similitude laws, the selection of appropriate instrumentation and test facilities, and the documentation of the results. This paper proposes guidelines for future fluid modeling expernnents of dense gas cloud dispersion. Performance envelopes are presented which bracket the “safe” regions in similitude parameter space for reliable model results. Recommendations are made for a minimum experimental program and associated documentation.
