A verification approach to thermoelastic steam turbine rotor analysis during transient operation

Dominiczak K., Banaszkiewicz M.

Transactions of the Institute of Fluid-Flow Machinery

2016

nr 131

55--65

This paper presents a verification approach to thermoelastic steam turbine rotor analysis. Neither temperature nor stresses are measured on the rotor surface in utility power plants. Therefore analysis of the steam turbine rotor can be verified only based on absolute and differential thermal expansion measurements in vicinity of the steam turbine. Absolute and differential expansion measurements and steam turbine fixed points arrangement allow to calculate thermal growth of the steam turbine rotor during transients. Thermal growth of the rotor can be a baseline for the calculation using a numerical model.
