Monbureau, E., S. Perry, AND D. Heist. Enhancements to AERMOD’s Building Downwash Algorithms based on Wind Tunnel and Embedded-LES Modeling. Building Downwash Summit, Research Triangle Park, NC, February 16, 2018.

Impact/Purpose:

Presented at the Building Downwash Workshop.

Description:

This presentation presents three modifications to the building downwash algorithm in AERMOD that improve the physical basis and internal consistency of the model, and one modification to AERMOD’s building pre-processor to better represent elongated buildings in oblique winds. These modifications are demonstrated to improve the ability of AERMOD to model observed ground-level concentrations in the vicinity of a building for the variety of conditions examined in wind tunnel and numerical studies.
