Mathematical modeling of the processes of combined heat and moisture transfer during storage and drying of raw cotton

Abstract

The article developed a multidimensional mathematical model of joint heat and moisture transfer processes in inhomogeneous porous bodies, considering internal heat and moisture release, heat, and moisture exchange with the environment. Based on the usage of an implicit finite-difference scheme with the second order of precision in time and space variables, an effective numerical solution for resolving issues with heat and moisture transmission has been created. Software was created for studying the processes of heat and moisture transfer during the storage and drying of raw cotton based on the developed numerical algorithm, making it possible to identify and forecast changes in temperature and humidity at arbitrary points of raw cotton with various sizes.
