Flow divergence in the turbulent premixed flames
Nihon Kikai Gakkai ronbunshu, 2014 In order to elucidate the flow divergence in the rich propane-air turbulent premixed flames, the flow fields of lean and rich propane-air and methane-air turbulent premixed flames of the identical conditions of laminar burning velocity and characteristic

Experimental study on premixed flame acceleration in closed pipe [PDF]
, 2013 An experimental study has been carried out to investigate the flame acceleration in closed pipe. A horizontal steel pipe, with 2 m long and 0.1 m diameter, giving length to diameter (L/D) ratio of 20 was used in this project.

Modelling of the turbulent burning velocity based on Lagrangian statistics of propagating surfaces [PDF]
Journal of Fluid Mechanics, 2019 We propose a predictive model of the turbulent burning velocity $S_{T}$ in homogeneous isotropic turbulence (HIT) based on Lagrangian statistics of propagating surfaces.

Journal of Thermal Science and Technology, 2006 The laminar burning velocity of pre-mixed hydrogen-air mixtures was measured in a fan stirred combustion bomb. Unstretched laminar burning velocities and Markstein lengths were obtained at 0.10MPa for equivalence ratios of 0.4, 0.6, 0.8 and 1.0 using ...

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.

Effect of Stretch on Local Burning Velocity of Premixed Turbulent Flames
Journal of Thermal Science and Technology, 2007 The effect of positive stretch on the local flame properties of turbulent propagating flames in the flamelet regime was investigated experimentally for methane-, hydrogen- and propane-air mixtures with lean and rich having nearly the same laminar burning
