本文提出了一种适用于气体燃烧器阵列产生的群火合并实验的火焰高度关联式。该相关性基于两个考虑：a）直到火焰高度的空气夹带与燃料燃烧的化学计量要求成比例，以及B）夹带的空气等于羽流的侧面积乘以夹带速度，夹带速度与距源的垂直距离的平方根成比例。这种相关性是适用于一系列的合并火灾，最近的结果验证。合并的调查组火灾的理由与旧的工作比较。
A correlation of flame heights is presented for recent experiments of merging group fires produced from arrays of gaseous burners. The correlation is based on two considerations: a) the air entrainment up to the flame height is proportional to the stoichiometric requirements for combustion of the fuel and b)the air entrained is equal to the side area of the plume multiplied by an entrainment velocity proportional to the square root of the vertical distance from the source. This correlation is applicable for an array of merging fires as recent results verify. Justification for merging of the investigated group fires is given together with comparison with older work.
