Numerical Analysis of Vibration and Noise of Ball Valve Based on Acoustic Vibration Coupling
Aiming at the noise problem of steam ball valves in engineering practice, this paper adopts the acoustic solid coupling numerical simulation method to study the structural modal characteristics of ball valves and the radiation vibration noise response of valve bodies and pipes. The research results show that the flow field generated in the pipeline behind the valve is the most turbulent,
