Modeling and Research of Temperature Changes and Moisture Content During Storage of Heterogeneous Porous Bodies in Open Space

A mathematical model of the temperature and humidity state of heterogeneous porous products during storage was developed, considering the influence of solar radiation, internal heat and moisture release, ambient temperature and humidity. An effective numerical algorithm was developed for solving problems of interconnected heat and moisture transfer during storage and drying of raw cotton in piles, based on the use of an implicit finite-difference scheme with second-order accuracy in time and space variables. The main characteristics of complex heat and moisture exchange problems were studied, and a software tool was developed for storing and drying agricultural products under the influence of natural factors.
