# Combustion properties of Dimethyl Ether

I have a C++ code which calculates the combustion thermodynamic variables (temperature, density) and the mass fractions of Dimethyl Ether for different equivalence ratio. I would like to check my results but I couldn't find anything on google. Most of the papers about DME that I've found show the laminar flame speed.

Please refer me to some paper or book if you know any. A graph showing the adiabatic flame temperature vs equivalence ratio would be ideal.

In 2014 it appears that Glaude, Sirjean, Fournet et al. published a paper that gives exactly the data you are looking for. See Figure 4 from their paper, which I have also included below.

Possibly relevant text from the paper:

the maximum flame temperature is obtained for slightly rich mixtures, at an equivalence ratio around 1.05-1.1, because of the lower impact of dilution by nitrogen when the amount of air decreases. At the strict stoichiometric conditions, the rate of the endothermal molecular dissociations is also at its maximum which tends to depress the temperature.

Also this next bit:

The results show that alcohols have flame temperatures comparable to those of conventional fuels, contrary to DME that develops significantly higher temperatures. This is consistent with the respective values of the heating values of these fuels and thermochemical equilibrium data.

I found the paper by Googling dme adiabatic flame temperature.

• I never expected to get such a complete answer! Thank you for that. Also, I googled dme adiabatic flame temperature again just to be sure and did not find that paper. I guess google knows you better than me! – solalito Oct 1 '15 at 10:30
