Wind tunnel analysis of flow and dispersion in cross-ventilated isolated buildings: Impact of opening positions

This paper presents a detailed experimental analysis of flow and dispersion by cross-ventilation in five generic isolated single-zone buildings with different opening positions. First, flow visualization is performed illustrating the highly transient flow and dispersion process dominated by a flapping jet with pronounced Kelvin–Helmholtz instabilities. Next, the mean velocity field, the turbulent kinetic energy field, the mean concentration...
