- According to the flow operating parameters of turbine during the downtime process , the convective heat transfer coefficient values between rotor surface and steam are calculated. The FEM transient temperature analysis model is setup to obtain the temperature distribution of rotor during the downtime process. Considering the centrifugal force and temperature load of rotor during the downtime process, the high temperature strength finite element model is setup using the dual linear intensive model. Then, the stress distribution of turbine rotor during the downtime process is obtained.
