No.2-8 O₂/N₂雰囲気中における球状微粉炭火炎伝播速度に及ぼす乱流強度の影響に関する研究

抄録

In this study, a new experimental apparatus in which the spherical flame propagation of coal particle cloud in a homogeneous turbulent flow field can be conducted has been developed. By employing the developed experimental apparatus, the effect of the turbulence intensity on the flame propagation of bituminous coal particle cloud was investigated. As a result, it was found that the flame propagation velocity increases with increasing turbulence intensity. This is considered to be caused by that the area of flame leading edge is increased with the turbulence intensity, same as the gaseous fuel flame propagation.
