Abstract:
The potential for using a large eddy simulation (LES)
computational fluid dynamcis (CFD) model to analyze
builidng indoor air quality (IAQ) and ventilation
problems was investigated. The LES model was developed
by the Fire Science Division of NIST to simulate the
transport of smoke and hot gases during a fire in an
enclosure. Based on an extensive literature review, the
application of the LES model to a test case, and
discussions with building industry contacts, it was
determined that this model offers unique capabilities
compared to other available CFD models and could be used
to make a significant contribution in studying issues of
current interest in the IAQ and ventilation field.
Recommendations for future work include evaluation of
the predictive accuracy of CFD, analysis of topics that
take advantage of transient simulation capability of
this model, and development of a strategy for U.S.
industry to apply CFD in the design process.
