Correlations of a flow around a cube and pressures on the roof

Abstract

The characteristics of a flow around a cubic model in a turbulent flow are experimentally studied by a wind tunnel test. Wind pressures at the windward edge decrease when velocity increase outside of the separated share layer. Negative pressures decrease at the center part of the roof when a strong circulation was formed above the roof. Wind pressures recovered at the leeward edge when a separated share layer reattaches at the leeward edge.
