    Abstract
  • Taking the centrifugal pressure atomizer as the research object, the effects of fuel temperature on the atomization characteristics of aviation kerosene under different pressures were experimentally tested and numerically simulated. The atomization characteristics of the fuel within the range of -20 ℃ to 50 ℃ were studied experimentally. The flow and atomization characteristics of the fuel within the range of -50 ℃ to 50 ℃ were simulated by numerical simulation. Results showed that the fuel pressure had little effect on the atomization characteristics; within the studied temperature range, the increase of temperature led to the increase of atomization angle, the decrease of Sauter mean diameter(SMD) and the increase of the non-uniformity of circumferential distribution. When the temperature rose from -20 ℃ to 50 ℃, the SMD decreased from 45 μm to 30 μm; the thickness of oil film increased with the decrease of fuel temperature, which was conducive to the improvement of the uniformity of fuel circumferential distribution, but led to the straight atomization droplets Track enlargement.
