Innovative Low Carbon, High Fuel Efficiency Power Generation Technology

布鲁内尔研究所工作的总体目标是通过理论分析、模拟和发动机测试来提高对理想燃烧系统的理解。布鲁内尔研究所第一阶段工作的目标是指定一种能够在相对较高的启动温度、较低的启动压力和膨胀体积的独特环境下实现最高燃烧和热效率的燃烧系统。初期工作将涉及确定燃烧系统要求的基准，具体地说，这将取决于对主要指定燃料(包括天然气和其他具有协同作用的潜在生物燃料)的现有经验数据的使用。这样的计算将提供一个基线。实际上，可能需要更快的模式(例如燃料分层、双燃料等)。此后，将采用正式的工程概念生成和选择程序来指定理想的燃烧系统类型和布局。然后，将使用现有的一维热力学(GT-Power)和/或三维CFD模拟程序对系统的性能进行详细评估。除了这项模拟工作外，Brunel还将对潜在市场和适用于该技术的燃料进行详细审查，并准备一份关于潜在未来机会的完整报告。此后，在Brunel的第二阶段工作中，将把单缸安装到发动机试验台上，并根据机械操作、气体交换效率、燃烧效率、热效率、燃油经济性和发动机排放来全面量化新单元的运行。这项工作将利用布鲁内尔现有的最符合行业标准的设施，并根据需要由工业伙伴提供开发支助。具体地说，将在额定功率和指定的其他关键地点对发动机运行和效率进行评估，以帮助理解新的运行模式。最后，这些测试结果将被用来完全关联发动机模拟，从而最大限度地理解所提出的发动机运行的新模式。

The overall goal of the work at Brunel would be to improve understanding of the ideal combustion system via theoreticalanalysis, simulation and engine testing.The objective of the first phase of work at Brunel would be to specify a combustion system that can attain the highestcombustion and thermal efficiencies within the unique environment of relatively high starting temperature, low startingpressure and expanding volume. Initial work would involve benchmarking the requirements of the combustion system.Specifically, this would be reliant upon use of existing empirical data for key nominated fuels (including natural gas andother potential biofuels offering synergy). Such calculations would provide a baseline. In reality faster modes may berequired (e.g. fuel stratification, dual fuel etc). Thereafter, formal engineering concept generation and selection procedureswould be adopted to specify the ideal combustion system type and layout. The performance of the system taken forwardwould then be evaluated in detail using existing 1D thermodynamic (GT-Power) and/or 3D CFD simulation codes. Inaddition to this simulation work Brunel would undertake a detailed review of potential markets and appropriate fuels for thetechnology, with a full report on potential future opportunities prepared.Thereafter, in the second phase of work at Brunel the single cylinder would be fitted to an engine test bed and theoperation of the novel unit fully quantified in terms of mechanical operation, gas exchange efficiency, combustion efficiency,thermal efficiency, fuel economy and engine-out emissions. This work would make use of the existing industry standardtest facilities at Brunel, with development support provided by the industrial partners as required. Specifically, the engineoperation and efficiencies would be evaluated at rated power and other key sites nominated to aid understanding of thenovel mode of operation. Finally, these test results would be used to fully correlate the engine simulation and hencemaximise understanding of the novel mode of engine operation proposed.
