K-1927 火花点火エンジンにおける火炎成長期のフラクタル次元推移(S24-4 噴霧・噴流と燃焼)(S24 燃料噴霧,ガス流動,混合気形成過程)

抄録

Turbulent propagating flame during flame growth period in an SI engine was visualized by a laser-light sheet technique. The time histories of fractal dimension of the wrinkling flame front were analyzed. The results show that the fractal dimension increases during flame the growth period and that the fractal dimension develops faster at higher engine speeds.
