Innovative Low Carbon, High Fuel Efficiency Power Generation Technology

布鲁内尔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。布鲁内尔第一阶段工作的目标是指定一种燃烧系统，该系统可以在相对较高的启动温度、低启动压力和膨胀体积的独特环境中实现最高的燃烧和热效率。最初的工作将包括对燃烧系统的要求进行基准测试。具体来说，这将依赖于使用现有的主要指定燃料的经验数据（包括天然气和其他具有协同作用的潜在生物燃料）。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）。然后，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，使用现有的1D热力学（GT-Power）和/或3D CFD模拟代码对系统的性能进行详细评估。除了这项模拟工作外，Brunel还将对该技术的潜在市场和合适的燃料进行详细审查，并编写一份关于未来潜在机会的完整报告。之后，在Brunel的第二阶段工作中，单缸将被安装到发动机测试台上，并在机械操作、气体交换效率、燃烧效率、热效率、燃油经济性和发动机排放方面对新装置的操作进行全面量化。这项工作将利用布鲁内尔现有的工业标准测试设施，并根据需要由工业伙伴提供开发支持。具体来说，将在额定功率和其他指定的关键地点评估发动机的运行和效率，以帮助理解新的运行模式。最后，这些测试结果将用于充分关联发动机仿真，从而最大限度地了解所提出的新型发动机运行模式。

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.
