Blade tip timing to determine turbine blade fatigue in high backpressure conditions

Blade tip timing to determine turbine blade fatigue in high backpressure conditions

This dissertation presents an approach to use blade tip timing measurements with finite element analysis to predict the fatigue life of a low pressure steam turbine last stage blade under high backpressure and low flow conditions. Material fatigue properties were determined through the extended univ...
