Abstract

The coupled process of vacuum freeze drying is modelled by a system of nonlinear partial differential equations. This article is focused on the submodel of heat and mass transfer in the absorption camera. The numerical treatment of the related parabolic partial differential equation is considered. The selected numerical results well illustrate the specific issues of the problem as well as some recently obtained results. Brief concluding remarks and prospectives for future investigations are given at the end.
