摘要

Abstract Sublimation of a humid porous body occurs commonly in food technology and thermal energy storage system . Especially, in accelerated freeze-drying, preservation of biological materials to be denatured is the prime interest. Despite the available literature on sublimation, there is a general lack of mathematical analysis of the effect of convection in the frozen and vapour regions, and rate of evaporation of water vapour in the vapour region. Therefore, it is essential to explore a mathematical model which accounts for these physical processes. This paper attempts to address these gaps in the modeling of sublimation of a humid porous body. For a specific form of the velocity profile, an exact solution of the current problem is obtained via similarity technique. Particularly, results from the current work are shown to be in strong agreement with the results of a previous work. The impact of various dimensionless problem parameters on the sublimation process is discussed extensively. Condition for sublimation limit is discussed. It is obtained that sublimation can take place only under limit of sublimation curve. It is found that, in the presence of convection, sublimation process becomes fast and the material requires less time than usual to sublimate. Furthermore, higher rate of evaporation of water vapour produces a lower temperature field and slower propagation rate of sublimation interface.
