Summary

Develops new local indices with the aid of numerical simulations to quantify air diffusion and contaminant dispersion. These are the local purging effectiveness of an inlet in a multi-inlet system and the local contaminant-accumulating index, which can be used to indicate the capacity of a ventilation flow to account for specific contaminant sources. In addition, by using the age-variation analysis, a scale independent of source strength is defined to forecast the dispersion of contaminants emitted at specific locations. Demonstrates the application of these new proposals with the aid of numerical simulations.
