1引言从安全与环保的观点出发,在水层之上的液态碳氢燃料层燃烧是一种普遍备受关注的火灾场景。实际上,当燃料层的沸腾温度超过水层的沸腾温度时,可能会引发严重的安全问题,因为这时会产生“沸腾开锅”现象,水层汽化喷出导致燃烧燃料的喷出,火焰高度和热辐射增加。发生在碳氢燃料层中的薄层沸溢现象具有同样重要的影响作用,这正是本项研究的主要内容。
1 Introduction From a safety and environmental point of view, the combustion of a liquid hydrocarbon fuel layer above the water layer is a generally-anticipated fire scenario. In fact, when the boiling temperature of the fuel layer exceeds the boiling temperature of the water layer, it may cause serious safety problems, because “boiling boiling” phenomenon occurs. The vaporization of the water layer causes the ejection of combustion fuel, Flame height and thermal radiation increase. The phenomenon of thin layer boiling over in the hydrocarbon fuel layer has the same important effect, which is the main content of this study.
