Embodiment Construction
[0020] The present invention will be further described through the embodiments below in conjunction with the accompanying drawings.
[0021] see figure 1 The invention relates to an experimental device for researching pollutant emission and diffusion of urban street canyon road motor vehicles, including a wind wall part, a street canyon building model, a pollutant emission vehicle model part, and a supporting measurement and control part.
[0022] The wind wall part 1 is composed of the wind wall 2 and the experimental section 3, with a wind speed range of 0-10m / s, which is used to provide the wind field required for simulating the street valley road under the action of the ambient wind. The experimental section 3 is composed of a transparent plexiglass plate, which is convenient for observing the experimental phenomenon.
[0023] The building model of the street canyon and the vehicle model for pollutant discharge are composed of a building model 11 on the leeward side of th...
