Modelling of low emissions combustors using large eddy simulation (MOLECULES)

Objective

Increasing air transport has increased pressure to reduce aero engine pollutant emissions. More efficient aero engines with lower CO2 emissions show higher combustor pressures and temperatures leading to increased NOx emissions, so new low NOx combustor technology is required. A detailed knowledge of the physical phenomena in the combustor is needed to improve today’s low NOx combustors. This knowledge can be provided by validated combustion CFD tools, lowering development cost and time by replacing expensive rig tests. MOLECULES will provide these validated CFD tools to the combustor designer. The method of Large-Eddy- Simulation is used, which is know to be capable of a better representation of highly turbulent flows. The validation tests will focus on typical features like strong swirl and mixing jets. A generic sector combustor will combine these features and provide benchmark CFD validation data.
