水幕抑制重气云扩散的研究进展

Research Progress of the Water Spray Curtain Mitigating Heavy Gas Dispersion

在分析重气云危险性的基础上,指出了水幕抑制重气扩散的方法。对水幕的结构、影响因素和作用机理进行了阐述,对目前国外进行的实验进行了简单的描述,并对各类模型的优缺点以及基本原理进行了概括,最后指出了未来水幕抑制重气扩散的实验和理论研究方向。

In this paper, based on the analysis of the dangerous of heavy gas cloud, the method of using the water spray curtain mitigating heavy gas dispersion is advanced. The structure, the contributing factors and mechanism of the water spray curtain is analyzed. The experiments on it at abroad are briefly described and the basic principals of models are concluded, as well as the advantages and disadvantages of every kinds of models. In the end, the direction for the future experirrental and theoretical studies of water spray curtain mitigating the heavy gas dispersion is proposed.
