摘　　要：随着燃气轮机应用领域逐渐增多,使用环境逐渐恶劣,船用燃气轮机逐步面临低温高湿的环境,压气机叶片结冰现象不可避免,严重的结冰现象会阻塞燃气轮机进气通道,减小通流面积,使压气机进气不均匀度增加,造成压气机工作效率降低。为了了解来流速度对压气机导向叶片结冰现象的影响,本文采用数值模拟的方法对某型2.5级压气机进口导叶进行了相关研究。结果表明:来流速度主要影响导叶结冰量,流速的增大会使得结冰量增多。With the increasing application fields of gas turbines and the increasingly harsh operating environment,marine gas turbines are gradually facing low temperature and high humidity environments.The phenomenon of compressor blade icing is inevitable,and severe icing can block the gas turbine intake channel,reduce the flow area,increase the unevenness of compressor intake,and cause a decrease in compressor efficiency.In order to understand the influence of inflow velocity on the icing phenomenon of compressor guide vanes,this paper uses numerical simulation methods to conduct relevant research on the inlet guide vanes of a certain type of 2.5-stage compressor.The results show that the inflow velocity mainly affects the amount of icing on the guide vanes,and an increase in flow velocity will lead to an increase in icing.
