摘要

以离心式压力雾化喷嘴为研究对象

对不同压力下燃油温度对航空煤油雾化特性的影响进行了实验测试和数值模拟研究

获得了燃油在喷嘴内的流动特性及温度、压力对燃油雾化特性参数的影响规律。实验研究了燃油温度变化范围在-20 ℃至50 ℃的雾化特性

数值模拟对燃油温度在-50 ℃至50 ℃范围内喷嘴内燃油的流动特性及燃油的雾化特性进行了数值模拟。结果表明:燃油压力对雾化特性影响不大;在所研究的温度范围内

温度增加会导致雾化角增大、索太尔平均直径（SMD）减小、周向分布不均匀性增大

在-20 ℃升至50 ℃时SMD由45 μm降低到30 μm;油膜厚度会随燃油温度的降低而增厚

有利于提高燃油周向分布均匀性

但会导致雾化液滴直径增大。

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.
