项目摘要

This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5)."PI: Qiao, LiProposal Number: 0927243This proposal targets on an emerging area of alternative fuels that have great significance for theeconomy, transportation and power generation systems. In our global, just-in-time economy, American competitiveness and innovation require an affordable, diverse, stable, and environmentally acceptable fuel supply. Simultaneous with efforts to increase the fuel efficiency and decrease the environmental impact of power generation systems, a new, diversified fuel source future is emerging in the marketplace as we move forward into the new century. Reliable design and optimization of advanced energy conversion systems will rely on a fully understanding of the chemical and physical properties of fuels. The next generation fuels are likely to be much different from current fuels. These fuels will be produced from alternative sources such as oil sands, oil shale, coal, as well as from a variety of biomaterials, all of which are fundamentally different from current petroleum-based fuels. New alternative fuels can be even more complex with increased fractions of compounds such as oxygenates napthenes and olefins, whose chemical properties and combustion kinetics are poorly known. There is an urgent need to understand the chemical and physical properties of alternative fuels.The overall objective of this proposal is to study ignition, burning rate, chemistry, and moleculartransport of surrogate and alternative fuels by a combined experimental and modeling study. Theobjectives will be pursued through an extensive experimental and modeling program that will include to: (1) Measure flame speed, minimum ignition energy, and Markstein number of surrogate and alternative fuel-air mixtures at elevated temperatures and pressures, with dilution, and for a wide range of fuelequivalence ratios; (2) Numerically simulate the planar laminar premixed flames, including complex chemical kinetics and molecular transport; (3) Numerically simulate the time-dependent flame propagation and study the effect of fuel Lewis number and stretch on flame dynamics; (4) Investigate the ignition behavior of extra lean alternative fuel-air mixtures using laser-induced spark ignition.Intellectual merit: The proposed research has the potential to (1) Provide a fundamental experimental database covering a wide range of parameters for validation kinetics and models ofsurrogate and alternative fuels that we have little knowledge of; (2) Improve our understanding of the effects of fuel chemistry and molecular transport on flame properties; (3) Improve our understanding of the ignition behavior of extra-lean alternative fuel-air mixtures by laser-induced plasmas. The research activities complement the PI?s education plan which is focused at: (1) Developing new courses in energy; (2) Developing high-school student research program with an emphasis of attracting high-school girls to engineering and science; (3) Recruiting women graduate students and providing research opportunities for women undergraduate students by collaborating with the Women in Engineering Program of Purdue University.The broader impact of the research proposed is significant. The results will lead to a fundamentalunderstanding of the ignition, burning, chemistry and transport properties of surrogate and alternative fuels, a complex and untested range of fuels. The results will improve our modeling and simulation capability for predictive design and thus will speed the development of the next generation of clean, fuelflexible and efficient energy conversion systems. The results will also assist in integrating new alternative fuel resources into the power generation devices, reducing our dependence on foreign oil. Additional broader impact contributions are associated with the educational activities, which are designed to benefit a broad group of individuals, especially women.
该奖项是根据2009年美国复苏和再投资法案(公法111-5)资助的。“PI:乔、李提案编号:0927243该提案针对的是对经济、运输和发电系统具有重大意义的替代燃料的新兴领域。在我们的全球,准时经济,美国的竞争力和创新需要一个负担得起的,多样化的,稳定的,环境可接受的燃料供应。在努力提高燃料效率和减少发电系统的环境影响的同时,随着我们进入新的世纪,一种新的、多样化的燃料源未来正在市场上出现。先进能量转换系统的可靠设计和优化将依赖于对燃料化学和物理特性的充分了解。下一代燃料可能与当前的燃料有很大不同。这些燃料将由油砂、油页岩、煤炭等替代资源以及各种生物材料生产,所有这些都与目前的石油燃料有着根本的不同。新的替代燃料可能会更加复杂,因为含氧化合物、环烷烃和烯烃等化合物的比例增加,而这些化合物的化学性质和燃烧动力学却知之甚少。目前迫切需要了解替代燃料的化学和物理性质,本提案的总体目标是通过实验和模拟相结合的研究来研究替代燃料和替代燃料的点火、燃烧速率、化学和分子输运。本文的研究目标是通过一个广泛的实验和模拟计划来实现的,包括:(1)在高温高压、稀释和大范围的燃料当量比下测量替代燃料和替代燃料-空气混合物的火焰速度、最小点火能量和Markstein数;(2)对平面层流预混火焰进行数值模拟,包括复杂的化学动力学和分子输运;(3)数值模拟了火焰传播随时间的变化规律,研究了燃料刘易斯数和拉伸对火焰动力学的影响;(4)研究了激光诱导火花点火对超稀混合气的点火特性。该研究有潜力(1)提供一个基本的实验数据库,涵盖我们所知甚少的代用燃料和替代燃料的验证动力学和模型的广泛参数;(2)提高我们对燃料化学和分子输运对火焰性质的影响的理解;(3)提高我们对超贫替代燃料-空气混合物的激光诱导等离子体点火行为的理解。研究活动补充PI?该教育计划的重点是:(1)开发新的能源课程;(2)开发高中学生研究计划,重点是吸引高中女生学习工程和科学;(三)通过与普渡大学妇女工程方案合作,招收女研究生,并为女本科生提供研究机会,拟议的研究产生了重大的广泛影响。这些结果将导致对替代燃料和替代燃料的点火、燃烧、化学和运输特性的基本理解,这是一个复杂且未经测试的燃料范围。研究结果将提高我们的建模和仿真能力,从而加快下一代清洁,燃料灵活和高效的能源转换系统的开发。研究结果还将有助于将新的替代燃料资源整合到发电设备中,减少我们对外国石油的依赖。其他影响更广泛的捐助与教育活动有关,这些活动旨在使广大群体,特别是妇女受益。
