LES for wind pressure acting on high-rise building wall surface in middle and high-rise city area on complex terrain

Abstract

LES was carried out to simulate the wind pressure acting on the high-rise building wall surface in the middle class and the high-rise city area on the complex terrain. The computed results were compared with the wind tunnel test results to confirm their applicability. As a result, the following things were confirmed. The flow field around the target building was influenced by the neighboring high-rise buildings. As for the wind pressure coefficients, the computed results coincided with the wind tunnel test results. The error of the computed results for the wind tunnel test results was almost in the range of 20%.
