Paper Title:
Online Calculating Models of Temperature and Thermal Stresses for Turbine Rotors
  Abstract

This paper presents the faster calculating models of temperature and thermal stress in a rotor based on two-dimensional axis-symmetry thermal conduction and thermo-elastic theory. The models can deal with nonlinear factors caused by temperature-dependant properties using modified Newton-Raphson iterative method. An example has been given to compare the results calculated by the models with those calculated by finite element method. It is shown that the analytical models gained have high accuracy. The iterative models can be used for online monitoring and control of turbine.
