Publisher's Synopsis
Minimum ignition energies of various methanol/air mixtures were measured in a temperature controlled constant volume combustion vessel using a spark ignition method with a spark gap distance of 2 mm. The minimum ignition energies decrease rapidly as the mixture composition (equivalence ratio, Phi) changes from lean to stoichiometric, reach a minimum value, and then increase rather slowly with Phi. The minimum of the minimum ignition energy (MIE) and the corresponding mixture composition were determined to be 0.137 mJ and Phi = 1.16, a slightly rich mixture. The variation of minimum ignition energy with respect to the mixture composition is explained in terms of changes in reaction chemistry.Knepper, Bryan and Hwang, Soon Muk and DeWitt, Kenneth J.Glenn Research CenterAIRCRAFT FUELS; PROPELLANT COMBUSTION; COMBUSTION CHEMISTRY; COMBUSTION EFFICIENCY; IGNITION; METHYL ALCOHOL; SPARK GAPS; STOICHIOMETRY...
