Overview of the Jack Rabbit II (JR II) Field Experiments and Summary of the Methods Used in the Dispersion Model Comparisons
This paper summarizes the Jack Rabbit II chlorine release trials conducted at the U.S. Army Dugway Proving Ground in 2015 and 2016 and provides on overview of comparisons of 17 widely used dense-gas dispersion models using the JR II data.
To assess the hazards of the releases of toxic chemicals to the atmosphere, comprehensive model systems are often used. This paper reviews knowledge gaps that were resolved in the past ten years by new theoretical and experimental research.
