摘要：
Condensation occurring in low pressure stages of steam turbines contributes to many losses in efficiency and damage to the stator blades such as corrosion and pitting. This problem has been observed profusely in power generation industries. The purpose of this study is to properly simulate the condensation and shock wave phenomenon at the last stage of the steam turbine and accordingly understand this phenomenon. Numerical simulation was conducted by using ANSYS Fluent and applying k-omega SST turbulence model. The results agreed with the experimental values.
