National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

User Friendly Approach for Modeling Air Dispersion of Chemicals in Industrial Facilities.

PB94151792

Publication Date	1993
Personal Author	Zemba, S. G.; Luis, S. J.
Page Count	143
Abstract	Current indoor air pollution models typically assume that contaminants are mixed throughout individual rooms. In general, this assumption is valid only if air movement is sufficient to disperse the pollutant. In the research, algorithms have been developed to model airborne concentrations of hazardous chemicals in large indoor spaces in which pollutants are not uniformly distributed. SIMULINK, a user-friendly software package for simulating dynamic systems, has been applied to simulate indoor air dispersion of contaminants. The modeling approach consists of dividing the indoor space into an interconnected network of rectangular volumes (parallelepipeds). Development and application of volume, exchange, and emission elements are detailed in the body of the report. The element techniques are best applied to problems in which ventilation data are adequate to characterize air flow patterns within the indoor environment.
