Primary Investigation on the Mechanism of Gravity Separation of the Droplets in the Steam Flow Field
A physical description of the formative cause and the ascension height of droplets is given according to the mechanism of gravity separation of the droplets in the steam flow field. In order to analyze the relationship between the height of gravity separation space and steam wetness，the dynamic single-drop model based on some simplified hypotheses is adopted，a comparison between the calculations and the experimental data is carried out. Based on this model and its analysis, the effects of the gravity separation space height，the velocity of the vapor flow，the droplet diameter as well as the initial velocity on the gravity separation efficiency are discussed in details. The qualitative description and analysis for the mechanism of gravity separation of the droplets in the steam flow field in this paper lays the groundwork for the qualitative analysis of the dynamic single-drop model.
