Publication year 2012 Abstract A series of wind tunnels tests are presented on a cube, equipped with a permeable outer layer. The influences of cavity depth and opening width have been investigated. This research shows that a wind direction of 75 degrees with respect to the considered panel gives the highest differential pressures relevant for cladding. For smooth approach flow conditions uniform cavity flows are found, with local effects near the openings in the reattachment zones. Large gaps affect the pressure equalization; hardly any effect can be observed when varying cavity depths. It is possible that measures leading to significant effects are outside the range of current practice Subject Building Engineering & Civil EngineeringSD - Structural Dynamics SR - Structural ReliabilityTS - Technical SciencesBuildings and InfrastructureArchitectureBuilt EnvironmentLocal wind loadsPressure equalizationBuilding facades To reference this document use: http://resolver.tudelft.nl/uuid:f76a80ee-5fc1-441c-8627-d4ec4c337bd7 TNO identifier 467112 Source Proceedings of the Seventh International Colloquium on Bluff Body Aerodynamics and Applications (BBAA7) Shanghai, China, September 2-6, 2012, 1-10 Document type conference paper Files To receive the publication files, please send an e-mail request to TNO Library.
