In order to investigate the atomization and ignition performance of coal-based Fischer-Tropsch synthetic aviation alternative fuels,a single-module rectangular combustor was used to experiment the atomization Sauter mean diameter(SMD)and lean ignition limit of the domestic coal-based F-T synthesis,traditional aviation kerosene RP-3 and 50:50 mixture of both fuels. Experiment results show that,the atomization and lean ignition limit of the three fuels share the same trends under normal temperature respective...
