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，需要产生阶跃变化的燃烧稳定性，排放和燃料的灵活性，为未来的燃气涡轮机发动机的改进。总体目标是提高这些发动机的环境性能、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运输部门的主要因素。燃气涡轮机发动机用于几乎所有的航空运输，以及大型发电厂和较小规模的分布式发电系统。这项研究的需要既来自环境/社会对减少污染物排放和通过采用替代燃料提高可持续性的需求，也来自加拿大主要公司以具有成本效益的方式实现创新的先进发动机设计的经济需求。由于加拿大生物质和煤炭资源丰富，在运输和发电方面使用非石油基替代气体涡轮机燃料的潜在好处特别具有吸引力。因此，这项研究工作的目的是产生新的知识和理解有关的燃烧和排放在高压下，以及热声耦合和燃烧动力学，从而带来了一个阶跃变化的改进，在预测和控制燃烧稳定性，同时减少排放和增加燃料的替代燃料的灵活性。这些目标将通过综合且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，并利用现有的世界级设施。数值研究将结合现有的高性能计算设施，采用先进的高保真计算方法和燃烧模型。
