Sumario: | A finite element modeling method to simplify the analysis of coupled thermal-structural model for the CLIC accelerating structure is presented. In addition, the results of thermal and structural analyses for the accelerating structure are presented. Instead of using a standard 3D computational fluid dynamics (CFD) method for solving problems involving fluid dynamics and heat transfer in 3D environment, one-dimensional fluid thermal elements are used. In one-dimensional flow, the governing equations of fluid dynamics are considerably simplified. Thus, it is expected that the computational time for more complex simulations becomes shorter. The method was first applied to several test models, which demonstrated the suitability of the one-dimensional flow modeling. The results show that one-dimensional fluid flow reduces the computation time considerably allowing the modeling for the future larger assemblies with sufficient accuracy. |
