Abstract: In the experiment, CO2 infrared analyzer and sampling probe are used to measure fuel spray characteristics of high-density kerosene and aviation kerosene downstream from a simple orifice injector. The effects of air flow velocity, pressure drop and distance from the injector on the fuel concentration distribution are studied. The test result show that under same condition the maximum concentration for conventional jet fuel is higher than that for high-density kerosene and the effects of air flow velosity and fuel pressure on penetration of maximum concentration are stronger for high-density kerosene than for conventional jet fuel.
