Mathematical Modeling of Hexafluorsilicate Ammonia Desublimation

The developed and software-implemented simplified three-dimensional mathematical model of the unsteady-state process of HFS desublimation into immersible vertical tanks with vertical finning is described. The study of regularities in the HFS desublimation process is performed by mathematical modeling. This algorithm has been implemented as an application package with a user-friendly interface. As a result, we have developed a two-dimensional non-stationary mathematical model of HFS desublimation in a reservoir consisting of several tanks, taking into account the presence of HPS convection and desublimation on the bottom wall of the tank, as well as the ellipticity of the upper and lower walls of the tank, which allows us to calculate a collector of any capacity, consisting of tanks of various types.
