Fundamental and Applied Studies in Combustion

该研究计划的目标是推进我们对社会和工业应用相关领域燃烧的基本理解。项目A -侧风中含有非烃液滴的燃烧排放：在全球范围内，能源行业每年燃烧约1390亿立方米的天然气，据信越来越多的部分含有非烃液体，如用于提高石油产量的“压裂液”。这些系统的排放量基本上是未知的。主要的研究问题是，以确定的氯基流体在排放剧毒氯化烃的火炬暴露于侧风时的命运。项目B -在模拟高达姆科勒数流动的燃烧速率中预混火焰的产生/破坏的作用：我们对非定常流动和燃烧速率之间相互作用的现象学理解不如对定常火焰的理解那样完善。大多数用于加热和发电的实际火焰都是湍流的，因此它们充满了不稳定性。不稳定的一种形式是产生和消灭火焰。本研究的目的是确保这些不稳定的影响是正确占在燃烧速率的预混flames.Project C -影响池畔边界条件浅池火灾：液态烃作为燃料，溶剂和食用油是无处不在的社会，他们被储存，处理和使用。由于它们的易燃性和造成损害的可能性，重要的是要了解意外点燃引起的燃烧。尽管池边条件影响深远，但其在设定燃烧速率方面的作用基本上是未知的。这项研究解决了这一缺点，以及探索新的抑制技术的选择。

The objective of this research program is to advance our fundamental understanding of combustion in areas that have applied relevance to society and industry. The specific projects are:Project A - Emissions from Flares that Contain Non-Hydrocarbon Droplets in Crosswinds: Worldwide, the energy industry flares approximately 139 billion cubic meters of gas annually, and an increasing portion is believed to contain non-hydrocarbon liquids, such as "fracking fluids" used to enhance oil production. The emissions from such systems are essentially unknown. The principal research issue is to determine the fate of the chlorine-based fluids in emitting highly toxic chlorinated hydrocarbons when the flare is exposed to crosswinds. Project B - Role of the Creation/Destruction of Premixed Flame in Modeling Burning Rates for High Damkohler Number Flows: Our phenomenological understanding the interactions between unsteady flows and burning rates is not as well developed as for steady flames. Most practical flames for heating and power production are turbulent, so they are rife with unsteadiness. One form of unsteadiness is to create and destroy flame. The objective of this study is to ensure that these unsteady effects are properly accounted for in the burning rate of premixed flames.Project C - Effects of Poolside Boundary Conditions on Shallow Pool Fires: Liquid hydrocarbons as fuels, solvents and cooking oils are ubiquitous in society where they are stored, handled, and used. Due to their flammability and potential for causing damage, it is important to understand the combustion resulting from accidental ignition. Despite their profound effects, the role of poolside conditions in setting the rate of combustion is essentially unknown. This study addresses this shortcoming, as well as explores options for novel suppression techniques.
