摘要

Detailed measurements on a low-rise building made at full scale and on a wind-tunnel model show a significant Reynolds number effect associated with the separated flow region on the windward roof slope of the building. Other possible causes for the observations are explored but are systematically eliminated. Brief details of the experimental procedure are presented together with significant results which suggest generalised corrections for scale effects. It is also proposed that the sensitivity of the separated flow at the windward eaves to Reynolds number has a secondary effect on the flow pattern downstream. Further detailed measurements are required to enable the correction factors to be generalised for other types of structure.
