Wind Tunnel Experiments on Cross-Ventilation Flow of Isolated Building with Contaminant Dispersion

摘要

Detailed wind tunnel experiments were performed on the cross-ventilation flow of an isolated building with contaminant dispersion. The distributions of not only the mean velocity but also the turbulent fluctuation and contaminant concentration were measured and investigated. First, the fundamental characteristics of the velocity and concentration fields in a cross-ventilated flow were investigated for the building. Next, the distributions of turbulent scalar fluxes in a cross-ventilated flow, which have been rarely reported, were also measured, and the scalar transport mechanism was examined based on the results.
