The proposed collaborative research effort will produce new knowledge, advanced engineering design tools, and innovative technology concepts needed to generate step change improvements in combustion stability, emissions, and fuel-flexibility for future gas turbine engines. The overarching goals are to improve the environmental performance, sustainability, and durability of these engines, while reducing development and maintenance costs. The vast majority (over 85%) of global energy is generated by combustion, including virtually all energy used in transportation. Canada is one of the most fuel-rich nations in the world, and combustion therefore will inevitably remain a major factor in Canada's energy and transportation sectors. Gas turbine engines are used in nearly all air transport, as well as in large-scale power plants and smaller-scale distributed power systems. The need for the research arises both from environmental/social demands for reduced pollutant emissions and increased sustainability through adoption of alternative fuels, and economic demands for major Canadian companies to achieve innovative new advanced engine designs in a cost-effective manner. The potential benefits of non-oil-based alternative gas turbine fuels for transportation and power generation are particularly attractive in Canada due to the abundance of biomass and coal. The aim of this research effort therefore is to generate new knowledge and understanding related to combustion and emissions at high pressures, as well as thermo-acoustic coupling and combustion dynamics, and thereby bring about a step-change improvement in prediction and control of combustion stability, while simultaneously reducing emissions and increasing fuel-flexibility for alternative fuels. The objectives will be achieved through a combined and highly integrated experimental and computational research program. The experimental effort will involve state-of-the-art measurement techniques and leverage existing world-class facilities. The numerical studies will bring to bear advanced high-fidelity computational methods and combustion models, in conjunction with available high-performance computing facilities.

拟议的合作研究工作将产生新的知识、先进的工程设计工具和创新的技术概念，为未来的燃气涡轮发动机带来燃烧稳定性、排放和燃料灵活性方面的逐步改进。总体目标是提高这些发动机的环保性能、可持续性和耐用性，同时降低开发和维护成本。全球绝大多数（超过85%）的能源是由燃烧产生的，包括几乎所有用于运输的能源。加拿大是世界上燃料最丰富的国家之一，因此燃烧将不可避免地成为加拿大能源和交通部门的主要因素。燃气涡轮发动机几乎用于所有的航空运输，以及大型发电厂和较小规模的分布式电力系统。这项研究的需求来自于环境/社会对减少污染物排放的需求，以及通过采用替代燃料提高可持续性的需求，以及加拿大主要公司以经济高效的方式实现创新的先进发动机设计的经济需求。由于加拿大拥有丰富的生物质和煤炭资源，非石油基替代燃气轮机燃料在运输和发电方面的潜在效益尤其具有吸引力。因此，这项研究工作的目的是产生与高压下燃烧和排放有关的新知识和理解，以及热声耦合和燃烧动力学，从而在燃烧稳定性的预测和控制方面实现逐步改进，同时减少排放并增加替代燃料的燃料灵活性。这些目标将通过结合和高度集成的实验和计算研究计划来实现。实验工作将涉及最先进的测量技术，并利用现有的世界一流设施。数值研究将采用先进的高保真计算方法和燃烧模型，并结合现有的高性能计算设备。
