Abstract

Curved vane demisters with high efficiency are widely used in power, chemical, and gas industries. To reveal the relationship between the separation performance and the basic geometric parameters used in the steam generator. In this paper, the influence of wavelength on droplet separation performance has been numerically studied. Additionally, the pressure drops, friction factor, and separation efficiency of the two-phase flow are numerically analyzed. Then, grade separation efficiency is numerically investigated, and the overall separation efficiency is obtained to evaluate the separation performance. It is found that a prolonged wavelength L can initially increase and thereafter decrease the separation efficiency. However, when the wavelength increases to a high level, continuously increasing the wavelength decreases the droplet re-entrainment mass source.
