Paper Title:
Numerical Study on Self-Consistency Centering Process of Periodic Symmetric Struts Support
  Abstract

In this paper,the simplified three-dimensional model of Periodic Symmetric Struts Support (PSSS) was established, which is applied to a certain type of gas turbine. The software of computational fluid Dynamics (CFD) and the standard k-ε turbulence model are used in the numerical simulation.To simulate the coupling problems of fluid and solid,the numerical models by considering the heat transfer problem coupling with the solid and fluid have been developed.The internal flow field in PSSS was numerically simulated by an effective method for solving integrated coupling problems. The temperature field and thermal deformation rule of the PSSS was obtained. Through comparison coordinate values of the checked points before and after thermal deformation, the impact of thermal deformation on bearing center level height under temperature load was studied. The centering process of the PSSS at high temperature state was verified.
