摘　　要：由于湿空气透平 (HAT)循环中进入透平的工质含湿量增加 ,使得透平性能变化很大。采用一元流动的分析方法 ,建立了基元级的性能模型 ,在基元级的基础上建立了对整个透平的性能计算模型和透平的临界状态计算模型 ,并计算了在给定透平几何尺寸及初始条件和背压不变的情况下 。Owing to the increase of moisture content in working medium entering the gasturbine of the humid air turbine (HAT) cycle, the performance of said turbine may be greatly varied. A performance model on basic element level has been established by using analytical method of one dimentional flow, and calculation models for entire performance and for critical conditions being established on the said basic element level basis. After completing the establishment of entire model, comparison and analysis of the performance under given geometric dimentions and initial conditions, as well as under situation of unchanging backpressure and differently increasing humidity, have been carried out.
