In the previous report, it was shown that without considering dissociation, the thermodynamic properties of the products of combustion varied almost linearly with 1/n, where n is the excess air factor. In the present report, the composition and the enthalpy of the products of combustion of air and a typical jet fuel are calculated, dissociation being taken into account. The results show that for the enthalpy of the mixture an approximate linear expression similar to that proposed in the previous report, i'(T, p, n)=i_D'(T, p, ∞)+i_<DΔ>'(T, p)・(1/n), can be used as a good approximation. The coefficients of the approximate expressions are presented for the three temperatures T=2000,2500,3000°K and for the five pressures p=0.1,0.5,1,5,10kg/cm^2. The error in i'(T, p, n) runs as high as 1.6 per cent, but they are less than 1 per cent in the range chiefly of interest in engineering.
