| Research Abstract |
This study investigated qualitatively the influence of molecular diffusivities of fuel and dilution gas as composing mixtures on burning velocity characteristics of micro-scale spherical laminar flames in the range of flame radius r_f<5mm, in order to examine combustion enhancement methods of micro-scale flames. It was clarified in lean mixtures having the same laminar burning velocity that as for fuel hydrogen with the larger molecular diffusivity as compared with methane and propane, and as for dilution gas carbon dioxide with the smaller molecular diffusivity as compared with nitrogen and argon had the tendency to improve its burning velocity of micro-scale flames.
