Разработан численный метод решения уравнений тепловлагопереноса, базирующийся на методе взвешенных невязок. Полученные результаты могут быть использованы для моделирования тепломассопереноса в различных технологических процессах, в строительной, пищевой и химической промышленности, а также в агрофизике.</p></abstract><trans-abstract xml:lang="en"><p>A mathematical model of moisture transfer in capillary-porous media is proposed. It is based on the equations of twophase filtration, isotherms of moisture sorption, thermodynamic equations of Kelvin and Klapeirone - Klausius . The numerical method of moisture transfer equations solving is developed on the basis of weighted residuals method. The results obtained can be used for simulation of heat and mass transfer in different technological processes, in building, food and chemical industry, and in agrophysics also.</p></trans-abstract></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Лыков А.
