We develop and apply an integrated modeling system to estimate fatalities from intentional
release of 17 tons of chlorine from a tank truck in a generic urban area. A public response …

Understanding mixing times for transient pollutants in mechanically ventilated rooms is
important for resilience and safety planning for accidental releases of toxic material. There is …

Accurate modeling indoor aerosol deposition and decay is an important step for exposure
assessment. High deposition rate reduces indoor pollutant concentration and results in …

Spatial concentration distribution of a chemical in an indoor environment is an important
factor in the evaluation of chemical nuisances. However, straightforward techniques for the …

The mixing processes of the aerosol particles from an outdoor environment in a ventilated
scale chamber were experimentally studied. The particles were classified into five groups by …

The release of hazardous materials originated from industrial/natural accidents or intentional
attacks within a compact urban environment can be disastrous. Once released, the …

Perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) have been detected
across the globe in a variety of media. The toxicity of these compounds and other precursors …

In industrial buildings, large cross-sections and obstacles lead to relatively low velocity in
the large space except in the vicinity of air supply jets. The dimensionless number that …

The well-mixing assumptions, uniform distributions of air temperatures and contaminant
concentrations and neglect of air momentum effects in a zone, used in multizone airflow …

With the increase of the computational capability, three-dimensional Lagrangian simulation
can now be applied to evaluate the particle pollution evolution in ventilated rooms. The …
