Mathematical model for estimation of desublimated solid layer thickness and surface temperature

Abstract EN

The thickness of the desublimatd solid layer is an important parameter required for evaluation of such desublimation process, especially in the case of solid layers production needed for special applications.

A mathematical model has been derived based on the analogy of heat and mass transfer to calculate the solid layer thickness of the desublimated layer during the operation period.

The prediction of thickness from the derived model is based on the data related to the applied experimental conditions as well as the physical properties of the vapour-gas mixture inside desublimator.

The calculated thickness from the model has been used to calculate the temperature gradient of the solid layer surface during the run period.
