摘要：

In this paper, EWF model in FLUENT was used to set a 3-D simulation scheme to study a series of flow behaviors when liquid film impinged on the attached plate on large-scale plate. The loss of falling liquid film at different flow rates impinging on the different large-scale attached plates was analyzed, and the condensation flow rates of falling liquid film which were collected by the reserve tank were compared, which fit well. Four processes of the liquid film behavior were divided and analyzed, in addition, the influence of the size of attached plate and flow rate of liquid film was studied. Besides, the relationship between the loss rate of liquid film and liquid film splash space number, and liquid film We when the liquid film impinged on the attached plate was obtained. Moreover, the shortcoming of EWF model in simulating falling liquid film impinging on attached plates was observed, which were attached with different weld heights. © 2020, Editorial Board of Atomic Energy Science and Technology.
