This work was carried out within the framework of an international cooperation between Germany and Japan. It was supported by the Deutsches Forschungszentrum für Luft-und Raumfahrt under the contract 50WM9448, and it was performed under the management of the JSUP (Japan Space Utilization Promotion Center) as a part of an R&D project concerning basic research on high-temperature air combustion technology, supported by the New Energy and Industrial Technology Development Organization.

N2 - The spontaneous ignition of isolated two-component fuel droplets was studied using n-decane (ND)/1-methylnaphthalene (MN) or ND/1,2,4-trimethylbenzene (TMB) as the components to be mixed. Both were n-alkane/aromatic mixture, one of the candidates for model fuels of multi-component commercial fuels refined from crude petroleum. ND exhibited two-stage ignition behavior, while the other two fuels did not and were less active. Ambient gas was air and droplet diameter was 0.7 nm. The experimental conditions that were varied were ambient temperature (Ta), ambient pressure, and initial mole fraction of ND in the liquid phase, Z, (0-1). It was common to ND/MN and ND/TMB that the two-stage ignition region was narrowed and vanished as Z decreased, and that t1, t2, and ttot increased monotonically with decreasing Z. However, TMB affected more than MN through its higher volatility. Numerical simulation with a fully transient one-dimensional model was used to interpret results. Original is an abstract.
