摘要
本文应用湍流流体力学理论推导了城市街道汽车排放微尺度湍流扩散模型,建立了运动方程及扩散方程的交错网格与变网格的有限容积法离散方程,并由此编制了全部计算机程序,为解决复杂下垫结构地面源污染物扩散过程的建模问题提供了途径。
Based on the theory of turbulent fluid dynamics,a micro scale turbu-
lent model for urban vehicular emission dispersion is built in the paper.The model is
discreted by finite volume method and solved by SIMPLE algorithm.The simulating
results show that the model and its programme work well.This study on the model
gives one way for modelling the dispersing process of the surface emitted pollutants,
such as vehicular emission.
