Computational-experimental modeling of processes in the protective shell with a passive condenser present in the passive heat-removal system

  • Published:
Atomic Energy Aims and scope

The modeling of the operation of a passive condenser based on a numerical solution of three-dimensional equations of hydrodynamics is examined. Questions associated with correct modeling of turbulent transport under free-convection conditions are examined. A model taking account of the dynamics of a condensate film and the conditions of heat and mass transfer on its surface is proposed for surface condensation. The results are used to develop recommendations for closure relations used in point codes with whose help design validation of a passive system removing heat from beneath the protective shell is performed.
