Doe is working with industry leaders on exploring leading-edge combustor design methods. This work is studying the effect of different fidelities of analysis as well as computational methods to reduce turnaround time. The goal is to easily produce more sophisticated simulations that were traditionally challenging for next generation commercial and military jet engines. The work has been a key enabler for the depth of understanding needed to meet emissions goals. This groundbreaking engine will deliver unprecedented reductions in emissions, noise, and cost of ownership as compared to current engines.

Used for advanced computer models and multidisciplinary experimentation in research activities including: atmospheric system research; environmental system science; and climate and Earth system modeling; as well as two national scientific user facilities—the Atmospheric Radiation Measurement Climate Research Facility and the Environmental Molecular Sciences Laboratory.

We have discovered that next-generation “green” low-emission technologies such as aircraft propulsion (jet engines) and energy systems (wind turbines) produce aerodynamic noise in the form of jet, fan, or wind turbine noise which poses a challenge for commercial viability. DOE laboratories are working with people in the industry to actively develop design technologies to understand and reduce such noise sources.
