Evaporation characteristics and efficient working area of multi-stage high pressure and temperature reducing valve

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