饱和蒸气湿度的理论计算

Theoretical calculation of saturated steam wetness

介绍用蒸发平面无因次负荷K_F代替以往常用的蒸发平面逸出速度ω''_0和汽部容积负荷R_V的依据。根据苏联的公式改写成易于计算的形式,以便理论上计算饱和蒸汽的湿度。

This paper explains the underlying basis for the substitution of the commonlyused evaporating surface escape speed W_0″ and steam volumn load R_r by eva-poration surfac non-dimensional load K_F.Based on the Soviet authorequation,a rewritten equation form convenient for calculationpurpose has been solved to facilitate the theoretical determination of thesaturated steam wetness.
