现代大型常规电站汽轮机所用的工质——高温高压过热蒸汽——在汽轮机通道中膨胀作功进入低压部分时,蒸汽中凝结出水滴,成为汽相和液相的两相介质,即所谓湿蒸汽。湿蒸汽中水滴的出现,一方面会引起动量 Working medium used in modern large-scale conventional power station steam turbines-high-temperature and high-pressure superheated steam-condenses water droplets in the steam as it expands into the low-pressure part of the steam turbine passage and becomes a two-phase medium of the vapor phase and the liquid phase, . Wet steam in the emergence of water droplets, on the one hand will cause momentum
