燃气轮机压气机进口部件积冰特性模拟研究
Numerical Study on Ice Accretion Characteristics of Gas Turbine Compressor Inlet Components
摘要
Abstract
In severely cold and humid regions,ice often accumulates in the air intake systems of ground and marine gas turbines.Currently,research on this issue is still in its early stages in China and abroad.Based on the principles of field calculations,water droplet behavior,and ice accretion thermodynamics,a prediction method for ice accretion under complex structural and flow field conditions has been proposed.A model of the inlet component of a 2.5-stage scaled compressor is established to simulate the flow field distribution,water droplet collection characteristics,and ice accretion characteristics under varying conditions of median volume diameter(MVD),liquid water content(LWC),wind speed,and temperature.The results indicate almost no ice accretes on the bell mouth.In the guide vane area,ice is primarily found between 10％to 50％relative blade height,concentrated on the whole pressure surface and only the leading edge of the suction surface.These findings are valuable for advancing the theory of gas turbine inlet ice accretion and guiding the design of anti-icing systems.关键词
