CFD analysis on internal flow field of liquid level control valve under steady working state.

At present, all kinds of liquid level control system is widely used in ground and underground storage tanks and other containers, which plays an important role to ensure the safety of production. Thus, it become an indispensable device of modern oil production and storage. In this paper, the governing equations of the internal flow field of the automatic control valve are established by using the basic theory of computational dynamic fluid and the RNG two equations turbulence model. And, the internal flow field of the automatic control valve under steady working state is simulated by using Fluent CFD software. Then, the pressure diagram, velocity profiles figure, velocity vector diagrams were obtained. It is believed that the research results of this paper have reference value for the further optimization of liquid level control valve. [ABSTRACT FROM AUTHOR]
