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.

该研究计划的目标是增进我们对与社会和工业相关的领域中的燃烧的基本理解。具体项目有： 项目 A - 侧风中含有非碳氢化合物液滴的火炬排放：在全球范围内，能源行业每年燃烧约 1,390 亿立方米天然气，其中越来越多的部分被认为含有非碳氢化合物液体，例如用于提高石油产量的“压裂液”。此类系统的排放基本上是未知的。主要研究问题是确定当火炬暴露在侧风中时，氯基液体会释放出剧毒的氯化碳氢化合物。项目 B - 预混火焰的产生/破坏在高达姆科勒数流燃烧速率建模中的作用：我们对不稳定流和燃烧速率之间相互作用的唯象理解并不像稳定火焰那样成熟。大多数用于加热和发电的实际火焰都是湍流的，因此充满了不稳定的情况。不稳定的一种形式是产生和摧毁火焰。本研究的目的是确保在预混火焰的燃烧速率中正确考虑这些不稳定的影响。项目 C - 池边边界条件对浅池火灾的影响：作为燃料、溶剂和食用油的液态碳氢化合物在社会中无处不在，在它们的储存、处理和使用中。由于它们的易燃性和造成损害的可能性，了解意外点火引起的燃烧非常重要。尽管池边条件具有深远的影响，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，并探索了新型抑制技术的选择。
