Characteristics of Non-stationary Thermal Stresses in Steam Turbine Rotor

The paper "Modelling Non-stationary Thermal Stresses in Steam Turbine Roto" presented at TMT 2004 shows the algorithm and the results of numerical modelling of non-stationary temperature fields, and the respective thermal deformations and stresses, caused by the steam turbine exit pressure change. From the presented general distributions of temperatures, deformations and stresses along the domain of complete rotor the general image about influence of the change of the exit pressure value on its thermal-stressed state is obtained. Simultaneously, some characteristic regions of rotor thermal-stressed state have been indicated which demand additional analysis: a) the central rotor bore ; b) the rotor low pressure part ; c) the disc of last turbine stage ; d) the rear-end labyrinth gland. It is in this work that the results of detailed analysis by means of parametric curves for cited regions for five values of the exit pressure are presented.
