项目摘要

In order to address energy related environmental issues of gas emissions and supply problems, there is an urgent need to investigate alternative fuels and energy systems such as hydrogen, syngas, dimethyl ether and bio-fuels. The combustion properties and the safety aspects associated with production, handling, transportation and storage of alternative fuels must be understood with a sufficient level of confidence in order to achieve public acceptance of wide spread utilization of these alternative fuels and to migrate to these possible fuel economies. A five-year experimental and computational research program is proposed to investigate the combustion characteristics and detonation properties of potential future alternative fuels. The objectives are to obtain new experimental combustion and detonation data particularly at high pressure conditions relevant to real storage and engine/gas turbine applications and to develop advanced mathematical/computational models capable of elucidating the fundamental mechanisms that underlie the evolutionary behavior of the detonation structure, the processes for flame acceleration, deflagration to detonation transition, dispersion/mixing dynamics and effect of the confining boundary and compressible turbulence in the alternative fuels systems. Chemical kinetics analyses are also carried out to explore the reaction sensitivity of the alternative fuels at different initial conditions, to design fuel blends for increasing safety, to balance the effect between ease of ignition and resistance to detonation (engine knock) in engine design, and to improve emission control. This project will systematically optimize and reduce the currently available kinetics models suitable for computational fluid dynamics using advanced mathematical techniques.

为了解决与能源相关的气体排放和供应问题的环境问题，迫切需要研究替代燃料和能源系统，例如氢，syngas，二甲基醚和生物燃料。必须以足够的信心来理解与生产，处理，运输和储存相关的燃烧性能以及与生产，运输和存储相关的安全方面，以便公众接受这些替代燃料的广泛利用，并迁移到这些可能的燃料经济体。提出了一项为期五年的实验和计算研究计划，以研究潜在的未来替代燃料的燃烧特性和爆炸特性。目的是获得新的实验燃烧和爆炸数据，特别是在与实际存储和发动机/燃气轮机应用相关的高压条件下，并开发出高级数学/计算模型，能够阐明基本机制的基本机制，这些机制是爆炸结构的进化行为的基础，对火焰的范围和混合式构造，构造的构造，构造的构造，分配性，分配性，分配性，分配性，分配性能，代码范围，代码，代码，构造的范围，构造的范围，代码范围内的构造，构成了。在替代燃料系统中。还进行了化学动力学分析，以探索在不同初始条件下替代燃料的反应敏感性，以设计燃料混合物以提高安全性，以平衡发动机设计中的易于点火和对爆炸的耐药性（发动机敲击）之间的效果，并改善发射控制。该项目将系统地优化和减少适用于使用高级数学技术计算流体动力学的当前可用动力学模型。
