Experimental study on flame characteristics of double fires in a naturally ventilated tunnel: Flame merging, flame tilt angle and flame height

Tunnelling and Underground Space Technology, 2021
A series of fire tests was carried out to investigate the diffusion flame characteristics of double fires generated from separated burners in a naturally ventilated tunnel, considering different heat release rates and fire separation distances.

Effect of fuel temperature on flame characteristics of supersonic turbulent combustion

Fuel, 2022
A comprehensive numerical study is undertaken to investigate the dynamics of hydrogen-air supersonic turbulent flames in a shear coaxial configuration. The effects of fuel temperature on the flow and flame characteristics are examined systematically. The

Flame characteristics of premixed H2-air mixtures explosion venting in a spherical container through a duct

International journal of hydrogen energy, 2021
The explosion venting duct can effectively reduce the hazard degree of a gas explosion and conduct the venting energy to the safe area. To investigate the flame quantitative propagation law of explosion venting with a duct, the effects of hydrogen ...

Radiative characteristics of flames

Combustion, Explosion, and Shock Waves, 1992
A method is proposed for determining the flame temperature from the location of the maximum of the spectral density of the radiation as determined from a finite number of frequency moments.
