- Abstract
- This article describes the design and performance testing of a turbine bypass valve trim. For effective control of velocity and pressure, a trim designed to have a tortuous path was designed. Computational fluid dynamics and FEM analyses were used in the design process. The valve, which was installed the designed trim, was tested. To evaluate its performance in the field, the valve was installed at a 900 MW combined power plant system for three months. The results showed that the pressure letdown was successfully controlled by the designed trim, and the noise level was reduced by about 8.1 per cent compared with the previous trim-type valve.
