Research on Fuel atomization technology in aero engine

Abstract

Recently, fuel combustion-related performances of aero engines are increasingly demanding, and their combustion quality directly affects their power, economy and emission characteristics, and a series of key performance indicators. The fuel atomization is the key link to determine the combustion condition. Therefore, this paper clarifies the mechanism of fuel atomization in aero-engines, studies the characteristics and methods of fuel atomization in aero-engines, and analyzes the influencing factors in the this process. The results indicate that lower fuel viscosity, smaller surface tension and appropriate temperature pressure, nozzle geometry, etc. can better enhance the fuel atomization performance. Herein, good atomization effect is the premise of efficient combustion, and it is important for energy saving and environmental protection. For the future development of engines, the rational organization of combustion is essential to improve their performance.
