A microscale, % -0jj"3, is introduced for turbulent diffusion flames, where t) and me, respectively, are the Kolmogorov scale and the flame Schmidt number. In terms of this scale, the turbulent mass transfer integrated over a length I of a liquid fuel is shown to be M' = pBL, % where p is the dynami

โฆ Synopsis
A general analytical relation for predicting mean luminous heights of buoyancy-controlled, turbulent diffusion flames is established. The relationship is based on a plot of experimental flame heights in correlation coordinates proposed previously, including extensive data recently published.
