The proposed UK Consortium on Turbulent Reacting Flows will perform high-fidelity computational simulations (i.e. Reynolds Averaged Navier-Stokes simulations (RANS), Large Eddy Simulation (LES) and Direct Numerical Simulations (DNS)) by utilising national High Performance Computing (HPC) resources to address the challenges related to energy through the fundamental physical understanding and modelling of turbulent reacting flows. Engineering applications range from the formulation of reliable fire-safety measures to the design of energy-efficient and environmentally-friendly internal combustion engines and gas turbines. The consortium will serve as a platform to collaborate and share HPC expertise within the research community and to help UK computational reacting flow research to remain internationally competitive. The proposed research of the consortium is divided into a number of broad work packages, which will be continued throughout the duration of the consortium and which will be reinforced by other Research Council and industrial grants secured by the consortium members. The consortium will also support both externally funded (e.g. EU and industrial) and internal (e.g. university PhD) projects, which do not have dedicated HPC support of their own.The consortium will not only have huge intellectual impact in terms of fundamental physical understanding and modelling of turbulent reacting flows, but will also have considerable long-term societal impact in terms of energy efficiency and environmental friendliness. Moreover, the cutting edge computational tools developed by the consortium will aid UK based manufacturers (e.g. Rolls Royce and Siemens) to design safe, reliable, energy-efficient and environmentally-friendly combustion devices to exploit the expanding world-wide energy market and boost the UK economy. Last but not least, the proposed collaborative research lays great importance on the development of highly-skilled man-power in the form of Research Associates (RAs) and PhD students of the consortium members, who in turn are expected to contribute positively to the UK economy and UK reacting flow research for many years to come.

拟议的英国湍流反应流联盟将利用国家高性能计算资源进行高保真计算模拟（即雷诺平均纳维尔-斯托克斯模拟（RANS），大涡模拟（LES）和直接数值模拟（DNS）），通过对湍流反应流的基本物理理解和建模来应对与能源有关的挑战。工程应用范围从制定可靠的消防安全措施到设计节能环保的内燃机和燃气轮机。该联盟将作为一个平台，在研究界合作和分享HPC专业知识，并帮助英国计算反应流研究保持国际竞争力。联合体的拟议研究分为若干广泛的工作包，这些工作包将在联合体的整个存续期间继续进行，并将得到联合体成员获得的其他研究理事会和工业赠款的加强。该联盟还将支持外部资助（例如欧盟和工业）和内部（例如大学博士）项目，这些项目本身没有专门的HPC支持。该联盟不仅在湍流反应流的基本物理理解和建模方面具有巨大的智力影响，而且在能源效率和环境友好性方面也将产生相当大的长期社会影响。此外，该联盟开发的尖端计算工具将帮助英国制造商（例如劳斯莱斯和西门子）设计安全、可靠、节能和环保的燃烧装置，以利用不断扩大的全球能源市场并促进英国经济。最后但并非最不重要的是，拟议的合作研究非常重视以研究助理（RA）和联盟成员的博士生的形式发展高技能人才，这些人反过来有望在未来多年为英国经济和英国反应流研究做出积极贡献。
