Outline of Final Research Achievements

In order to ensure the presence of self-stabilized concept for miniaturization, two approaches were taken; first, we introduce the precise numerical simulation with detail kinetics model how the flame interacts with burner and what is the key reaction to it. Additionally we have proposed the evaluation measure of excess-enthalpy under various kinds of fuel and ejecting condition. Second is to examine the character of the thin-film (Pt-WO3)-type gas sensor, which might be useful to understand the species (H2) distribution inside the microburner. So called "gaschromic reaction" is utilized for this purpose and the fundamental characters of this sensor are properly examined/reported.
