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.

Measurements of Horizontal Flow in the Vicinity of a Building: A Field Study from June to December 1999.

DE200515011631

Publication Date	2004
Personal Author	Gouveia, F. J.; Shinn, J. H.
Page Count	30
Abstract	The pattern of flow around a discrete, yet architecturally complex building is measured through the use of arrays of 2-D sonic anemometers. When the measurements are grouped according to upwind wind direction and normalized by the upwind wind speed, the resulting average vectors reveal persistent patterns of divergence, separation zones, and lee eddies. Additional measurements were made investigating specific details of flow. A pair of 10-m towers supported four levels of anemometers to explore vertical profiles of wind immediately upwind of the building, in an exterior alcove of the building, and in the lee of a line of tall trees. The measurements described in this report may be compared with physical and computational models of flow.
