Combustion and Propulsion Research Group

Professor Ömer L. Gülder                                  

I joined UTIAS in November 2001 and I lead an experimental and computational research program in Combustion and Propulsion. I collaborate with Profs. Clint Groth and Adam Steinberg (UTIAS),  Drs. David Snelling, Fengshan Lui, Hongsheng Guo, and Greg Smallwood (National Research Council Canada), and with several other colleagues from Europe.

My group's research has been in the field of turbulent combustion, premixed flame propagation, soot formation in combustion, radiation and chemical kinetics interactions, development and use of experimental optical diagnostics in combustion systems, gas turbine combustion, combustion in reciprocating engines, structure of fuel sprays, fuel technology, combustion of pyrophoric fuels and radiation from flames. I am the author and coauthor of more than 250 papers in these areas. I served on the editorial boards of Combustion and Flame, International Journal of Engine Research, and International Journal of Thermal Sciences. I also served on the Board of Directors of the Combustion Institute between 2000 and 2012, and I was the Chair of the Canadian Section of the Combustion Institute from 1991 to 2001.
