The main difference is that the "saturation value" of the second-phase material in the first is set by the "transfer number", B, defined as the enthalpy differenc between the bulk of the gas and the gases adjacent to the liquid surface divided by the enthalpy increase undergone by the liquid to achieve vaporization. This value is if the order of 10.0 for many fuels. Therefore a value of cmdtc around 10/(1+10) has the right order of magnitude. It is the value employed here. Inspection of the profiles shows that, when the extra-air factor is chosen to be about 1.4, a significant amount of unburned vapour enters the gas stream.
