Cfd and wind tunnel simulations are complementary due to their inherent limitations wind tunnel tests apply to any hypothesis, but are limited by the tunnel wall interference/blockage, the model details, and even the distortion of the model. Wind tunnel modeling and analysis of wind effects on low-rise buildings wind tunnel modeling is a robust technique which allows determination of wind effects on buildings and other structures due to complexity of flows and induced wind loads, other techniques can not be reliably used in practical analyses of such effects.
