Abstract

We consider a new promising approach to the combustion of water-saturated hydrocarbon fuels in the form of foamed emulsions, stable combustion of which can sometimes be maintained at a water content above 90% mass %. Theoretical analysis and numerical simulations demonstrated the basic physical mechanism determining these broad combustibility limits, which consists in the natural spatial separation of the zones of fuel combustion and water evaporation. During combustion, the foam predominantly breaks up into emulsion drops. Nonstationary regimes of combustion are determined by the foam structure. The obtained data define applicability of the proposed concept of combustion of water-saturated foamed hydrocarbon emulsions.

高含水量泡沫乳液的燃烧极限

摘要

我们考虑一种新的有前途的方法来燃烧泡沫乳液形式的水饱和烃燃料，该稳定的燃烧有时可以在水含量超过90％（质量）时保持。理论分析和数值模拟表明，决定这些广泛的可燃性极限的基本物理机制在于燃料燃烧和水蒸发区域的自然空间分隔。在燃烧期间，泡沫主要分解成乳液滴。不稳定的燃烧状态由泡沫结构决定。所获得的数据定义了所提出的水饱和泡沫烃乳液的燃烧概念的适用性。
