Tim Lieuwen


Office: Guggenheim 363
Phone: 404.894.3041


  • B.S., Engineering, 1995, Calvin College (Grand Rapids, Michigan)
  • M.S., Mechanical Engineering, 1997, Georgia Institute of Technology
  • Ph.D., Mechanical Engineering, 1999, Georgia Institute of Technology


Dr. Lieuwen is active in both instruction and research programs. His interests lie in the areas of acoustics, fluid mechanics, combustion, and signal processing. He is responsible for teaching several courses in the areas of fluid mechanics, aeroacoustics and combustion. His research activities involve both theoretical and experimental work in combustion, flame-acoustic wave interactions, combustion noise, and development of ultrasonic diagnostic techniques.


Combustion and acoustics focused research in the fields of energy and the environment, including:

  • Combustion of alternative and coal-derived fuels
  • Dynamical combustion phenomena including flashback, blowoff, and combustion instabilities
  • Acoustics in inhomogenous media and thermoacoustics
