Three-Dimensional Modeling of Rocket-Propellant Dispersion
2007
Yamada, T. | Bunker, S.
The purpose of this study was to demonstrate the feasibility of using a small computer to operate a three-dimensional atmospheric model to forecast the transport and dispersion of airborne hazardous materials at Vandenberg Air Force Base (VAFB). The contractor investigated the feasibility of using the three-dimensional atmospheric models HOTMAC (Higher Order Turbulence Model for Atmospheric Circulations) and RAPTAD (Random Puff Transport and Diffusion) to meet the objective of the project. HOTMAC is a mesoscale atmospheric model that can forecast three-dimensional distributions of wind speed, wind direction, turbulence, temperature, and water vapor. RAPTAD is a Lagrangian puff code based on the Monte Carlo statistical diffusion process. The center location and standard deviation of concentration distribution for each puff axe computed by use of wind and turbulence modeled by HOTMAC. Then concentration at any location is computed by summation of concentrations contributed by all the puffs.
