Experimental study on fuel concentration distribution of high-density kerosene

The CO2 infrared analyzer and sampling probe were used to measure the fuel spray characteristics of high-density kerosene and conventional 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 were studied. The test result showed that under the same condition, the maximum concentration for conventional jet fuel is higher than that for high-density kerosene and the effects of air flow velocity and fuel pressure on penetration of maximum concentration are stronger for high-density kerosene than for conventional jet fuel.
