Abstract The modeling of the indoor concentration distribution produced by sources and sinks of pollutants is complicated by nonuniform mixing within the indoor settings. Two common approaches to predicting the concentration distribution are to either treat the indoor volume as containing multiple compartments with uniform mixing within each, or to treat the entire indoor volume as a single uniformly mixed compartment with an empirical mixing factor m that is introduced to correct for nonuniform mixing. We review the literature on m and show that this empirical approach violates a basic principle of conservation of mass. We propose a new conceptual model for the case of a source of pollution in an indoor setting.
Supplementary Notes Presented at the American Society for Testing and Materials Symposium, Methods for Characterizing Indoor Sources and Sinks, Washington, DC., September 25-28, 1994. Prepared in cooperation with World Health Organization, Geneva (Switzerland).
