本文介绍了一个研究城市建筑物间污染物扩散的拉格朗日模型。流场由客观分析提供（Rockle（1990）Ph.D.论文，Vom Fachbereich Mechanik，der Technischen Hochschule达姆施塔特，德国），并被调整以满足连续性方程。从所得到的质量一致场的拉格朗日扩散参数被删除。采用非均匀场中的三维拉格朗日扩散模型计算了建筑物间的污染物分布。几个例子进行了研究，并与风洞测量。
A Lagrangian model to study the dispersion of pollutants between urban buildings is described. The flow field is supplied by an objective analysis (Rockle (1990) Ph.D. thesis, Vom Fachbereich Mechanik, der Technischen Hochschule Darmstadt, Germany) and is adjusted to satisfy the continuity equation. From the resulting; mass consistent field the Lagrangian diffusion parameters are eliminated. A 3-D Lagrangian diffusion model in a nonhomogeneous field is applied to calculate the pollutant distribution between the buildings. Several examples are studied and compared to wind tunnel measurements.
