   <abstract xml:lang="ru">
    <p>Целью данной работы является численное решение задачи определения среднего времени пребывания в метантенках цилиндрической формы с одинаковыми геометрическими размерами, но с различным расположением патрубков загрузки и выгрузки органического субстрата. Трехмерная нестационарная задача была решена с использованием программного пакета Comsol Multiphysics 3.5а. </p>
