COMMIX-1A three-dimensional in-vessel simulation of the FFTF thermal hydraulics
Description
Three-dimensional in-vessel simulation of the FFTF thermal hydraulics has been performed with the COMMIX-1A computer code. The COMMIX-1A code employs the porous media formulation in which the concept of volume porosity, surface permeability, distributed resistance, and distributed heat source is used to model the internal structures. The governing equations of conservation of mass, momentum, and energy are solved as a boundary-value problem in space and as an initial-value problem in time. In the present report the calculated results for the study-state reactor full-power operation are presented, and are compared with experimental measurements, where applicable. Based on the COMMIX calculations, thermal stratification is observed in the upper plenum, together with eddy-type recirculation. Comparison of measured flow rates and temperaturs at selected locations has been satisfactory
