Key Findings

Further Funding


Description	Direct numerical simulation (DNS) of turbulent premixed flames have been conducted, with realistic chemistry and detailed transport. The main findings: 1. At high turbulent Reynolds numbers and high Karlovitz numbers, there is a regime change in combustion mode; 2. At elevated pressures, cellular flame structures are observed due to flame instabilities. 3. Turbulence changes the chemical pathways. The work contributed to the continuation of the consortium under the EPSRC grant No. EP/R029369/1.
Exploitation Route	The findings have significant implications for the design and operation of gas turbine combustors. The results may be exploited with industrial partners Rolls-Royce and Siemens Industrial Gas Turbines.
Sectors	Aerospace Defence and Marine Energy Environment Transport

Description	Joint exploitation of the research with Southeast University and Jiangsu Yanxin Sci-Tech Co. Ltd. (http://en.chinayanxin.com/) has resulted in the development of a low-NOx combustor for the petrochemical industry. The new design was guided and optimised through detailed CFD predictions for the flow, temperature, and NOx distributions. The improved combustors have seen a 50% increase in annual sales worth an extra ¥40M (£5M) for the company.
