| Lattice-Boltzmann method (LBM) and finite volume method (FVM) simulations were performed for the VVER-440 type nuclear reactor. Triangular rod bundle array has pitch-to-diameter ratio (P/D) of 1.35 is used in order to validate the Smagorinsky (LES) subgrid scale turbulence model implemented in lattice-Boltzmann framework. The FVM simulations are handled using ANSYS Fluent 13.0 CFD Solver. For both LBM and FVM, turbulence model study was accomplished and the post-processed turbulence quantities, velocity profiles and Reynolds stresses were compared with the experimental data produced by Trupp and Azad, 1975. The comparisons show that lattice-Boltzmann simulations are in good agreement with the finite volume method based LES simulations and also used experimental data.Following the completion of validation process of lattice-Boltzmann code, the spacer grid effect on the flow is then … |
