To provide steam of appropriate quality and to improve the efficiency of steam-water separation over corrugated plates, it is necessary to study the condensation behavior of wet steam moving over a corrugated plate separator. In this paper, classical nucleation theory and a droplet growth model are used to describe the process of wet steam condensation on corrugated plates. The CFX software water droplet condensation model was employed to simulate the process and to allow analysis of the characteristics of wet steam condensation. The results show that: (1) the nucleation rate increases gradually over time and exhibits a positive correlation with the temperature of the wet steam, (2) departure from the saturated state decreases gradually along the flow direction, leading to a concurrent decrease in the steam condensation rate and (3) the steam condensation rate is elevated with increases in the local pressure gradient. |
