“…The analysis of transient thermal behaviors was acted on the basis of transient turbulent flow simulation and turbine valve experiment. It indicates that the second separated flow causes non-uniform heat transfer [18]. Benefiting from the advantages of fluid-structure coupling and structural mechanics, scholars carried out the failure analysis of valve body and predicted fatigue life.…”

A well understanding on the evaporation characteristics and efficient working area of MSHPTRV (multi-stage high pressure and temperature reducing valve) is important for improving the performance and safety of MSHPTRV. The water spraying and evaporation model are integrated into the flow model of MSHPTRV. Compared with the experimental data, the model can show the thermal process well. The flow characteristics and interaction between steam and droplets are presented. On this basis, the increase rate of entropy Sdis is adopted to analyze the thermodynamic loss and innovatively determine the efficient working area of MSHPTRV. The results show that the pressure reducing effect of the second orifice plate is prominent, which accounts for 41.6% of the total pressure drop. The "steam-water layer" is formed at the boundary of steam and water. At the inlet of second orifice plate, the maximum Sdis is 0.782, and the downstream of second orifice plate is the efficient working area of MSHPTRV. The length of evaporation section increases with the droplets diameter significantly.
