摘　　要：以HAT循环中饱和器为研究对象 ,讨论了实验研究的相似条件。在简化条件下建立了饱和器内部多相流的控制方程 ,并给出了相应的边界条件 ;对这些方程进行了无量纲化处理 ,根据微分方程的不变性原理 ,得到了饱和器实验研究中应遵循的相似准则 ,并对这些准则在实验中作用进行说明 。With the humidifier of a humid air turbine (HAT) cycle serving as an objective of study similarity conditions are discussed during the conduct of experimental research. Under simplified conditions equations of control of multi-phase flows in the humidifier were established along with corresponding boundary conditions. These equations were subjected to a non-dimensionalized treatment. On the basis of an invariance principle of differential equations similarity criteria were deduced, which the humidifier shall comply with during the experimental research. Some explanations are given concerning the role being played by these criteria during experiments. Moreover, some major issues requiring due attention during the tests of the humidifier are also presented.
