摘要

在高寒高湿的地区，地面和船用燃气轮机进气系统易发生积冰现象，目前国内外对燃气轮机进气积冰研究仍处于起步阶段。该文基于外流场、水滴场以及积冰热力学计算原理，提出复杂结构及流场条件下的积冰预测方法。建立某型燃气轮机2.5级模化压气机复杂进口部件模型，对不同平均粒径(median volume diameter，MVD)、液态水含量(liquid water content，LWC)、风速和温度条件下流场分布、水滴收集特性以及积冰特性进行模拟研究。结果表明，喇叭口壁面几乎不产积冰；导叶区域积冰主要集中在相对叶高10%~ 50%内，积冰在压力面区域均有分布，在吸力面区域仅集中在前缘。该文研究结果为完善燃气轮机进气积冰理论、指导相关防冰系统设计提供一定参考。

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.
