| Outline of Final Research Achievements |
Flame near the wall is largely affected by the chemical boundary condition as well as the thermal and fluidic boundary conditions. The chemical boundary condition depends on the surface reaction, and recently it is proved that it has an important role in the macroscopic combustion field through chemical quenching by radical adsorption and enhancement of gas-phase reaction/autoignition by desorption of the radical from the surface. In the present study, near-wall combustion mechanisms when the surface chemical materials are modified, and thermal and chemical flame-to-wall interaction is investigated in detail. For that purpose, a series of measurements of flame temperature, radical distribution using microscopic laser induced fluorescence, and surface reaction measurement in non-combustion field using electro-discharge-based radical formation as well as numerical simulations with detailed gas-phase and surface reactions are carried out.
