船用燃气轮机装置在海上运行,吸入的空气中含有水分,水分的多少可用相对湿度来衡量.在常温常压下仍可以视为理想气体.但热物理性质(定压比热Cp和气体常数R等)与干空气不同,对发动机热力过程产生的影响不可忽略,所以针对空气湿度的不同对某型燃气轮机性能的影响进行研究和探讨,为船舶在实际运行中提供理论参考.%The ship gas turbine plant works on the sea, it will inhale some water vapor in the air. The amount of water vapor can be expressed by comparatively humidity. Under the normal temperature and normal pressure,the air which the gas turbine inhale can be viewed as ideal air, but the thermodynamics physics performance parameters including setting pressure specific heat CP and air constant R is different from the ideal air,which can influence the thermodynamics process can't be ignored. This paper will study the influence of gas turbine performance consideration different air humidity.
