Abstract

The developed and software-implemented simplified three-dimensional mathematical model of the unsteady-state process of UF6 desublimation into immersible vertical tanks with vertical finning is described. The study of regularities in the UF6 desublimation process is performed by numerical modeling. The results of calculations on the average capacity of vertically finned tanks with a volume of 1.0–4.0 m3 at varied collector pressure, cooling agent temperature, and tank geometry are presented. It is demonstrated that an increase in the number of fins in a varied heat and mass transfer regime appreciably improves the average capacity of vertically finned tanks and reduces the time of their filling.
