Dispersion Patterns In A Heterogeneous Urban Area

Fernando E. Camelli, Rainald Löhner, Steven R. Hanna


A LES numerical modeling of flow in cities is presented. In three different scenarios,
FEFLO-URBAN was used to analyze flow and dispersion patterns. First, a realistic urban
setting in Tysons Corner, Northern Virginia, where the building geometry was obtained through
blueprints; second, the MUST experiment conducted in the U.S. Army Dugway Proving Ground
Horizontal Grid test site in Utah; and finally, a scenario in New York City as part of a collaborative
effort supporting the design for the MSG05 Tracer experiment in the Madison Square
Garden area.
