Abstract

The invention discloses a street canyon motor vehicle exhaust pollutant concentration estimating system. The system can obtain street canyon pollutant diffusion and distribution situations by adopting a CFD numerical simulation method according to urban road vehicle flow, canyon geometric structure and other data and is strong in operability. In addition, the system makes monitoring of air pollution degrees in all urban regions operable and flexible, facilitates drawing of an air pollution concentration distribution diagram of the local region, facilitates determination of a heavy pollution zone of the local region and analysis of air pollution causes in the local region and provides a scientific and reasonable basis for formulation of local region exhaust pollution treatment measures.

Description

technical field [0001] The invention relates to the technical field of environmental forecasting, in particular to a system for estimating the concentration of exhaust pollutants from motor vehicles in street canyons. Background technique [0002] With the rapid advancement of industrial automation and the improvement of people's living standards, the number of urban motor vehicles has increased rapidly, and motor vehicle exhaust emissions have become the main source of urban pollutants, seriously affecting the quality of life of urban residents. Different from traditional coal-based industrial pollution, motor vehicle exhaust emissions are low, close to the height of human breathing zone; the rapid growth of motor vehicle ownership leads to high density of emission sources. At the same time, exhaust emissions are mostly concentrated in urban streets, and the diffusion conditions are poor, which is likely to cause long-term retention of pollutants. Therefore, the diffusion o...
