Numerical Investigation of Operational Conditions Effects on the Annualr Seal Rotordynamic Characteristics of a 1400-Mw Canned Motor Reactor Coolant Pump

The annular seal between the stator and rotor substantively act as a bearing which affects the rotordynamic characteristic of the Reactor Coolant Pump (RCP) during its long-time service. The target of this work is to have a major research about the operational conditions effects about inlet pressure and rotational speeds on the rotordynamic characteristics of the annular seal in the RCP. For solving the annular seal frequency-dependent...
