Kaoru Maruta is a professor and deputy director of Innovative Energy Research Center at Institute of Fluid Science, Tohoku University, Japan. His research interests are new concept combustion technology, microcombustion, combustion under microgravity, mild combustion and plasma-assisted super-lean combustion in SI engines. He is a fellow of the Combustion Institute, an executive board of IDERS, an associate editor of Combustion Science and Technology, and in the editorial board of Progress in Energy and Combustion Science. He is a winner of Mega-grant Project supported by Russian Government and recipients of international and domestic awards including Minister of Education Award in Japan.
Microcombustion study at Tohoku University based on the idea of excess enthalpy combustion is introduced. “Flame chromatography” using a micro flow reactor with a prescribed temperature profile has been applied for examining ignition and combustion characteristics of various fuels including hydrocarbons, alcohols, syngas and even weakly reacting refrigerant. Flame dynamics as well as validation and modification of reaction kinetics have been addressed by the present reactor. Recent studies using this method for stabilized cool flame, surrogate fuels for practical fuels and refrigerant are discussed.
