Abstract
A computational procedure suitable for modeling both
vertical and horizontal steam generators is presented.
The procedure consists of a one-dimensional model for the
whole steam generator and a CFD model for the secondary
side. The three-dimensional two-phase CFD simulation of
the secondary side utilizes the porous medium
approximation and the mixture k-e turbulence model.
One-way coupling between the models is used, in which the
surface temperatures of the heat transfer tubes are
considered as a boundary condition for the CFD
simulation. A stationary state and two pressure
transients, a pressure rise and a pressure reduction, for
the PWR PACTEL steam generator are calculated and the
internal circulation on the secondary side is analyzed.
PWR PACTEL is a test facility, located at Lappeenranta
University of technology, in Finland, which was
constructed for research activities associated with the
European Pressurized Reactor (EPR).
