BACCHUS-3D/SP. A computer programme for the three-dimensional description of sodium single-phase flow in bundle geometry

Creators

Description

The computer programme BACCHUS implemented at KfK includes a steady-state version, a two-dimensional and a three-dimensional transient single-phase flow version describing the thermal-hydraulic behaviour of the coolant (sodium or water) in bundle geometry under nominal or accident conditions. All versions are coupled with a pin model describing the temperature distribution in fuel (or electrical heaters) and cladding. The report describes the programme from the viewpoints of the geometrical model, the mathematical foundations and the numerical treatment of the basic equations. Although emphasis is put on the three-dimensional version, the two-dimensional and the steady state versions are also documented in self-consistent sections. (orig.)

Abstract (German)

Das Computerprogramm BACCHUS, das im KfK implementiert ist, enthaelt eine stationaere, eine zwei- und eine dreidimensionale transiente einphasige Version zur Beschreibung der Thermohydraulik eines Kuehlmittels (Natrium oder Wasser) in einer Buendelgeometrie unter Nominal- oder Unfallbedingungen. Alle Versionen sind mit einem Stabmodell zur Beschreibung der Temperaturverteilung im Brennstoff (oder dem elektrischen Heizer) und der Huelle gekoppelt. Im Bericht wird das Programm hinsichtlich des geometrischen Modells, der mathematischen Grundgleichungen und ihrer numerischen Behandlung beschrieben. Obwohl die dreidimensionale Version im Vordergrund steht, werden auch die zweidimensionale und die stationaere Version in sich abgeschlossen dokumentiert. (orig.)
