AbstractA wind tunnel test and numerical simulation are carried out for a building model with a setback. High positive peak and low negative peak pressures are observed experimentally on roofs and walls of this building in dominant local pressure zones. Large scale l simulations using LES are carried out for meshes in different resolutions to clarify the phenomena. A 30m long computational domain is constructed to conscientiously model the wind tunnel section including spires, fences and block roughness. Wind speed power spectral densities, pressure coefficients and local pressure distributions show good agreement with experimental results in case of the high mesh resolution, which can reproduce the power spectrum of wind flow in a high frequency region. These results also confirm the high accuracy and reliability of the numerical results as well as experimental results. Based on simulated time-averaged streamlines, the flow pattern around the models "" are visualized and examined. Conical and horseshoe vortices in the complex three dimensional flows are observed near the dominant local negative pressure zones.
