Abstract

See full text

The present invention discloses a convenient and small near-ground atmospheric-boundary-layer wind tunnel and its application in the human exposure risk assessment. This near-ground atmospheric-boundary-layer wind tunnel comprises a wind tunnel body and a reflux stabilizer; the wind tunnel body comprises a natural wind injection device and a simulation test device, with the natural wind injection device, the simulation test device and the reflux stabilizer connected in sequence; the natural wind injection device comprises a pipe fan, a swirl mixing pipe, a diffusion homogenizer, and a cyclone distribution pipe connected in sequence; the diffusion homogenizer is provided inside at the center with an inner member for preventing flow separation; and a static mixing spiral rod is welded on the inner wall surface of the swirl mixing pipe. The measurement of the atmospheric-pollutant environmental migration and transformation behavior through this wind tunnel reduces the floor area of the wind tunnel and saves the investment. The wind tunnel can allow research of the environmental migration and transformation process of near-ground atmospheric pollutants in a local area and assessment of the impact of the near-ground atmospheric pollutants on the population health.
