Use of CFD Simulation to Measure the Effects of Floor Plan Shape and Building Height on Pedestrian Wind Comfort and Wind Safety

Abstract:

The rapid development of computer technology, especially computer performance, enabled significant development of CFD simulations. Nowadays advanced computer technology, have CFD simulations in the construction sector irreplaceable position in determining the impact of wind on buildings and people. In comparison to the measurements in wind tunnels, represent much faster and cheaper method with comparable results. Presented paper deals with identifying and assessing the impact of floor plan and building height of nine different pairs of highrise buildings on pedestrian wind comfort and safety in their immediate surroundings. For simulation was selected computer program OpenFOAM. The results of simulations for all of nine cases were compared and evaluated according to the requirements of the Dutch standard NEN 8100:2006.
