碩士 === 中正理工學院 === 兵器系統工程研究所 === 88 === Abstract The purpose of this work is to study the response of a phase Doppler Particle Analyzer ( PDA ) to the seeding ；The results show that the PDA instrument is well suited to the detailed spray investigations. The influences of different fuel injection patterns in combustor are discussed in this present. Both the local pressure oscillation and its frequency response may be used to analyze the combustion results by these fuel distribution arrangements. Results show that the arrangements in fuel injection must obey the rule that it should inject a certain amount of liquid fuel into the main recirculation zone or the flame holding mechanism in the dome of combustor ；Two types of baffles, which are set at the inlets outlet, are used to suppress the second-tangential pressure oscillation in the testing of a four inlets engine；the effects of different injector angle on the combustion instability of engine was investigated by the testing .The fuel injectors are installed at the inside wall of the inlet end； Low frequency oscillation occurs in the combustor as the most of liquid fuel is concentrated in the front dome.
