Keywords:
mathematical model, finite-difference scheme, heat transfer, moisture transfer, raw cottonAbstract
A multidimensional mathematical model of simultaneous heat and moisture transfer processes in inhomogeneous porous bodies is proposed, 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 has been created. Based on the developed numerical algorithm the software was created for studying and analysing the processes of heat and moisture transfer during the storage and drying of raw cotton in open areas which makes it possible to identify and forecast changes in temperature and humidity at arbitrary points of cotton.
