Abstract

A porosity model for the simulation of two-phase flow on the secondary side of both horizontal and vertical steam generators is presented. The Euler-Euler multiphase model of the Fluent CFD code is used for the simulation of the secondary side. The outer wall temperatures of the heat transfer tubes obtained by performing an APROS simulation of the steam generator are used for generating the source terms for the enthalpy equations. The model is tested by performing simulations for a horizontal steam generator of Loviisa VVER-440 nuclear power plant and a vertical steam generator of the PWR-PACTEL test facility.
