Numerical Study of the Effect of Notches on Main Cooling Water Pump Shaft Failure

The Main Cooling Water Pump (MCWP) is critical in geothermal plants, since failure reduces capacity and increases downtime. This study investigates the fatigue failure of an ASTM A276 Type 316 stainless-steel MCWP shaft at an Indonesian geothermal plant, fractured by a grinding notch from overhaul. The unresolved probl...

Trade-off between thermal performance and fatigue life of grooved thrust bearings in steam turbines using an FSI-based approach

Thrust bearings are essential for maintaining the axial stability of steam turbine rotors under continuous high-load operation. At the Tenayan coal-fired power plant, repeated thrust bearing overheating caused several unit trips despite lubrication flow improvements and material replacements. This study investigates th...
