海岸线熏烟扩散模式中岸距与烟囱有效高度关系的研究

Research on the Relations Between the Distance from Shoreline and the Effective Height of Chimneys in Diffusion Model of Shoreline Fumigation

在海岸线熏烟扩散模式中,Lc、He与hf的值及其相互关系是决定海岸线熏烟是否发生及其严重程度的主要参数。任意处的hf是由自然状况决定的,而Lc和He的值是由人为确定的。本文在深入分析海岸线熏烟的发生原理、过程及模式的基础上,确定了在其他条件相同时,不同Lc处,Cfm所对应的He的值,以及Lc与He之间的关系式及其危险值,为沿海或沿大型湖泊等水体附近的工业项目的Lc及He的选取及合理性检验提供了依据。

In the diffusion model of shoreline fumigation, Lc, He, hf and the correlations between them are the main parameters to decide whether there will be a serious shoreline fumigation. A hf rests with the nature conditions, but the L and He is determined by the people, On the basis of in - depth analyzing the principle, processes and pattern of shoreline fumigation, this paper identifies the He corresponding the Cfm along with changing Lc, while other conditions unchanged. The text provides basis for selecting and testing Lc and He of the industrial projects nearby the coast or great lakes and or other great water bodies.
