摘要
有毒、易燃易爆工业危险物质的泄漏扩散已成为公共安全领域的热点问题之一,本文综述了该领域国内外已有的重气扩散的数学模型,从简单的经验模型到中等复杂度的工程应用模型和高度复杂的研究型三维模型,分析了这些模型的优缺点和应用现状,指出了三维数学模型模拟精度的提高和计算瓶颈的解决等是数学模型应用的进一步发展趋势,并提出了若干扩散数学模型研究急需开展的方向:针对井喷等特定重气扩散情形的自有知识产权数学模型开发、统一界面的全过程模拟软件研制以及加强重气扩散数学模型与GIS、GPS的融合等。
This paper intends to make a general review over the status-quo of the research tendencies of math-models of the industrial hazardous material leakage and dispersion. As is known, industrial hazardous materials are by nature inflammable, explosible, and/or toxic, and therefore, turn to be a spotlight in the field of public security. The present paper has given a general survey over the currently used methods of numerical simulations for heavy gas dispersion from the simplistic empirical models to scaled engineering project models, including models of medium complication and 3D simulated models of highly complicated nature. In addition, it has analyzed the merits and demerits of the above said models, respectively, as well as their current application conditions. Further developmental trends have also been commented on how to raise the accuracy of 3D simulations by overcoming the bottleneck problems involving the numerical calculation methods. And, last of all, the paper has also made recommendations for the fields likely to find mathematical modeling potentially applicable, such as the development of models for special scenario, software of uniform interface for overall phases＇ simulation, combination with GIS/GPS and so on.
