• Description:
  Algorithms developed to model airborne concentrations of hazardous chemicals in large indoor spaces in which the pollutants are not uniformly distributed were described. The approach used involved dividing the indoor space being studied into a network of rectangular volumes called parallelepipeds. A volume element modeling the first order differential equation integrating the mass of the pollutant in the volume representative of each parallelepiped was described. The influence of physical processes such as contaminant emission, local air supply and exhaust, and chemical removal due to reaction and deposition was evaluated. Exchange elements specified the rates of air transfer between adjacent volume elements and these elements were used to generate interconnected grids for modeling pollutant dispersion. The authors conclude that this model is useful in determining the causes of indoor air pollution in situations in which adequate ventilation data are available. [Description provided by NIOSH]
