Abstract:
To reduce the environmental and climate impact of combustion in engines,
there is an incentive to replace conventional transport fuels (Diesel, heavy fuel oil)
with alternative fuels such as natural gas, LPG, alcohols, or even ammonia.
To guarantee safe and efficient operation of engines, insight in the autoignition
and flame properties of these fuel alternatives at high pressure is required.
Characterization of chemistry at high pressures is challenging, however, both
experimentally and theoretically. In this presentation, it is discussed how our
knowledge of the high pressure oxidation chemistry for simple hydrocarbons,
alcohols, and amines is advanced through a close interaction between experimental
work, chemical kinetic modeling, and high level theory. Special emphasis is put on
the pre-ignition chemistry, which is studied in specially designed high-pressure flow
reactors. The improved knowledge of the high pressure kinetics of combustion allows
us to predict with greater confidence ignition, fuel consumption rate, pollutant
formation, and safety issues. The practical application of this knowledge will
be discussed.
Bio:
Peter Glarborg is Professor of Chemical Engineering at the Technical University of Denmark,
where he has taught since 1996. Peter is an Associate Editor of Combustion and Flame and
he was Program Co-Chair for the 36th International Combustion Symposium in Seoul in 2016.
Peter has published about 300 research articles in archival journals. He is working broadly in
the field of combustion and harmful emission control, with special emphasis on developing
detailed reaction mechanisms for high-temperature gas-phase processes.
