CFD-simulation of OECD V1000CT2 with advanced turbulence models


CFD-simulation of OECD V1000CT2 with advanced turbulence models

Höhne, T.

CFD calculations have been performed for the themalhydraulic benchmark V1000CT-2.
The numerical grid model was generated with the grid generator IC4C (ICEM-CFD) and the preprocessor ANSYS CFX and contains 4.7 Mio. tetrahedral elements Different advanced turbulence models were used in the numerical simulation The best agreement with the Kozloduy experiment at the core inlet shows the DES simulation. Strong fluctuations occur in the downcomer of the RPV.
The results show a clear sector formation of the affected loop at the downcomer, lower plenum and core inlet. The maximum local values of the relative temperature rise in the experiment amount 97.7% and in the calculation 97.3%
Deficits: Estimation of experimental values at the core outlet to the core inlet, interpolation
