The Design and Numerical Study on Flow Characteristics of High Temperature and High Pressure Steam Trap

Abstract:

In order to solve the problem of the flow-induced vibration under high temperature and high pressure when opening or closing the steam trap, sleeve was designed and three-dimensional numerical simulation of the internal turbulent fluid field was performed by using Fluent of computational fluid dynamics software. When sleeve is installed ,the results show that flow-adjusting characteristic is equal percentage for different travels , meanwhile, meet the rules that low flow rate is at small opening and large flow is at maximum open degree. It is benefited to suppress the generation of pressure fluctuation and pipe-vibration. This paper will provide a reference for the design of more excellent performance steam trap.
