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.

Transport Modeling of Industrial Ventilation.

PB2005105193

Publication Date	1997
Personal Author	Squires, K. D.
Page Count	74
Abstract	The focus of work performed under Grant R01 OH03052 was development of new computational models appropriate for predicting contaminant transport in the complex turbulent flows encountered in industrial ventilation applications, with an emphasis on contaminants comprised of dense particulates. The newly developed models are based on large eddy simulation (LES), a more accurate technique for predicting turbulent transport than methods currently used in engineering practice. The goal of this work was to extend LES to prediction of turbulent flows transporting small particles which do not follow the flow and to validate the model against experimental measurements from well-defined test problems.
