A microscale,η β ∼ η β 1 , β , respectively, are the Kolmogorov scale and the flame Schmidt number. In terms of this scale, the turbulent mass transfer integrated over a length l of a liquid fuel is shown to beM = μBl β ,B is the transfer number,B = (Y O ∞ Q O M O - h w )h f g ,Y O is the mass fraction of oxidizer, Y O ∞ its ambient value, Q the heat release for a simple global chemical reaction, and ν O and M O the oxidant stoichiometric coefficient and molecular weight, respectively,h w = c p (T w - T ∞ ),c p the specific heat of gas, T w and T ∞ the fuel and ambient temperatures, respectively, andh f g the heat of evaporation. It is shown by the similarity between the mass and momentum transfer,M B = C f ,C f being the drag coefficient, and thatM BM B) B = 0 = C f C f ) B = 0 = 1B) 3 ,B = 0 for the case without boundary mass transfer. The agreement between the model and the sparse experimental data is reasonable.
