Progress in Developing an Open Burn/Open Detonation Dispersion Model

Abstract

This paper briefly summarizes the model development effort which is divided into operational and research components. In the following, we give a brief discussion of the background and overall model design and then describe the operational model components for instantaneous (OD) and short-duration (OB) sources; the OD model is a Gaussian puff approach whereas the OB framework consists of integrated-puff and plume models. The combined OB/OD model includes: 1) a continuous treatment of dispersion as the release condition varies from instantaneous to continuous, 2) cloud and plume rise obtained from appropriate entrainment models, 3) cloud and plume penetration of elevated inversions, 4) relative (puff) and total dispersion based on modern scaling concepts for the planetary boundary layer (PBL), and 5) a capability for the use of onsite profiles of wind, temperature, and turbulence from a mobile meteorological platform. The current GB/GD model focuses on the unstable PBL.
