Mathematical Equations behind CONTAM Simulation Tool

[Xinxiu Tian]

Hi Stuart,

I am working with a CONTAM steady state building model. I would like to know how CONTAM calculates the steady state zone-specific total airflow rates, which is the number inside of the red box in the picture I attached. Also, how CONTAM calculates the steady state zone-specific contaminant concentrations. May you please provide the documentation of these mathematical equations? 

Thanks,

Xinxiu

The CONTAM User Guide contains an extensive "theory" section (chapter 8).  There are also references to journal publications that support the work.
