Abstract:

The main purpose of this evaluation was to develop a hybrid modeling approach to toxic vapor diffusion modeling in the vicinity of buildings or structures which influence plume behavior. The hybrid approach combines the use of physical wind-tunnel and computer modeling in order to improve the site-specific performance of gaussian puff and box-type hazard response models by accounting for pollutant trapping, redirection, and dispersion enhancement caused by the presence of structures. The documented project included reviewing the capability of wind-tunnel modeling to simulate nearfield dispersion, conducting wind-tunnel tests for a sample Air Force base environment, assessing limitations of the current AFTOX and SLAB models for treating dispersion in the vicinity of obstacles, development of a sample hybrid model, and suggesting a methodology for generalized application of hybrid modeling at any Air Force installation.
