Experiments and a correlation of turbulent burning velocities.

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 1985
層流燃焼速度SLは同じで,層流火炎の反応域厚さが互いに異なる混合気について乱流燃焼実験を行った.その結果,反応域厚さδは乱流燃焼速度STに大きく影響し,SLー定で同じ乱れ強さu'ではδが薄いものほどST/SLが大きいことが明らかになった.次に(ST一.SL)/u'で定義された乱れ強さの有効度は,整理に用いた本論文と他のいくつかの実験結果について,反応域厚さと乱れの平均空間尺度の比が増すにつれて減少することが示された.

IMPACT OF THE NOZZLE ANGLE, DISTANCE BETWEEN BURNERS, AND N2 ON BURNING VELOCITY OF THE DIFFUSOIN COUNTER FLAMES

Journal of Engineering and Sustainable Development, 2020
The achievement of precise measurements on the laminar diffusion flames plays a big role in the process of realizing a wide flames range. Despite most of fuel is likely burnt in the turbulent combustion, there is still data requirement for the data on ...

Effect of Inert Gas on Turbulent Burning Velocities.

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 1999
In our previous works, the preferential diffusion effect was found to play an important role in premixed turbulent combustion characteristics, where nitrogen was added as an inert gas to several fuel/oxygen mixtures. In this study, the inert gas is changed to Ar, He and CO2, and the relationship between the turbulent burning velocity and the diffusion ...
