摘要
介绍了建筑物尾流扩散的特征 ,分析了排放高度对尾流扩散的影响 ,通过建立蒙特卡罗方法 ,模拟了位于立方体形建筑物上方的烟囱在不同释放高度的排放 ,探讨了排放高度对建筑物尾流扩散特征的影响 ,并就现有预测模式所存在的问题进行了讨论。
The paper describes the dispersion characteristi cs in building wake in detail and emphasizes on the analysis of effects of emissio n height on wake dispersion. The emission of sources at various heights above a cubic building is simulated through establishing Monte Carlo simulation method ( also called particle random walk simulation). According to the simulated results . The effect of emission height on the dispersion characteristics in building wa ke is studied and the relevant issues existed in the present prediction models i s also discussed. (
