【 摘 要 】

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.
