Research Areas and Descriptors


Tim Lieuwen began his academic career in 1999 as an Assistant Professor in the School of Aerospace Engineering after completing his Ph.D. in mechanical engineering in the Woodruff School.


My research is in the area of understanding and control of ultra low emissions

Laser Doppler velocimetry measurements in an aircraft engine combustor.  Measurements such as these will enable the development of cleaner burning aircraft engines, capable of burning future fuels.

combustion systems for power or propulsion applications. This includes combustion control, characterization of fundamental combustion properties, and understanding dynamical combustion phenomenon. Oftentimes, these problems require a strong interdisciplinary approach requiring understanding of acoustics, fluid mechanics, and control. Research involves alternative fuels, bio-derived fuels, hydrogen and other potential fuel sources for the future. Major funding is provided by the US Department of Energy, NASA, and industry.

If you like making fire, making noise, and saving planet all at the same time, you'll enjoy working on these research problems! Typical employers are in the propulsion and energy sectors, the government, or national labs.
