A112 メタン予混合微小球状伝ぱ層流火炎の燃焼速度特性に関する研究(燃焼科学と技術の新展開I)

抄録

This study is performed to examine experimental the burning velocity characteristics of the methane-premixed micro-scale spherical laminar flames with the flame radius r_f < approximately 5mm, and also macro-scale laminar flames with r_f > 5mm for comparison. The mixtures have nearly the same laminar burning velocity and different equivalence ratio φ(0.8〜1.0). The radius and the burning velocity of micro-scale flames are obtained by using sequential schlieren images recorded under appropriate ignition conditions. The results show that the burning velocity of methane-premixed micro-scale flames has tendency to increase with increasing r_f and approach that of macro-scale flames.
