The Calculation of the Transient Temperature Field and the Thermal Stress Field of Steam Turbine Rotor With Finite Element Method |
| |
| Abstract: | This paper discusses the problem of the axisymmetric transient temperature and thermal stress field calculation With finite element method. Based on the transient thermal equilibrium principle, the Way that determines transient steam temperature and convection coefficient in steam—seald gland is presented. With the IP rotor of 200MW steam turbine as an example, transient temperature and thermal stress field calculation is made Finally, some useful data and conclusions are obtained. |
