It has been recognized in recent years that models developed to describe the dispersion of neutrally buoyant plumes or clouds ire inadequate to describe negatively buoyant heavy vapor clouds formed, for example, by accidental spills of volatile liquids. Subsequently, numerous models have been proposed to describe heavy vapor clouds, often with nonexistent or very limited comparison with experimental data, beyond those used to adjust or “calibrate” model parameters. We compare here several heavy vapor dispersion models on a nearly consistent basis against the same sets of experimental data.
