Abstract
This memorandum describes some initial work to construct a wind field library consisting of pre-computed building-aware mean wind and turbulence fields obtained from a high-resolution, high-fidelity computational fluid dynamics (CFD) model for a specific urban area; namely, for the downtown area of Vancouver and the surrounding environs for use in “on-demand” CFD in support of emergency response applications (requiring quick turnaround times) for the 2010 Winter Olympic Games. To this purpose, mean wind and turbulence field simulations were obtained for 32 wind directions using CFD over a model (computational) domain of 255 km2 (with a building-aware region of 10.4 km2 at 9-m horizontal resolution) centered on downtown Vancouver. An example illustrating the application of the wind field library for the rapid calculation of urban dispersion for a release of a hazardous material in downtown Vancouver is provided.
