Outline of Final Research Achievements

The objective of the present work is to obtain the microscopic understanding on plasma-assisted combustion by experiments and simulation. It has been understood that the production of atomic oxygen via collision between molecular oxygen and high-energy electron, which is produced in the plasma, in the premixed zone of the flame is the origin of activated combustion reactions. In the case with the addition of water vapor, it has been suggested that OH radical, which is produced by electron impact dissociation of H2O, is the origin of activated combustion reactions.
