| Popis: | A three-dimensional porous media model has been implemented for the secondary side of the horizontal steam generator of a VVER-440 plant by using the ANSYS FLUENT 12.0 code. The primary circuit is solved with the APROS system code and the outer wall temperatures are interpolated to the CFD model. The necessary models for the heat and mass transfer and drag are implemented as User Defined Functions in the Euler-Euler two-phase model of the FLUENT code. The steady state full power operation of the steam generator is solved. The calculated result is compared to void fraction and flow velocity measurements at a few points. The shape of the surface level is compared to observations. |
