Scale Analysis of Hydraulic Test of Tube Support Plate in Steam Generator Based on Computational Fluid Dynamics

Various analysis focused on hydraulic performance of TSP model with different scale and structure was carried out by CFD calculation. The comparison of calculation results show that the characteristics, which are not nearly influenced by the wall of flow channel, such as flow resistance, flow field and mass flow distribution in the regular hexagon TSP models with structures of 1/3rd and 1/2nd orifice, are basically consistent with the ones in the prototype. The structure can be applied in the design of TSP model for the hydraulic test.
