Преимуществом алгоритма расчета является быстрое, по сравнению с численным интегрированием, получение элементов матрицы прямых взаимных поверхностей, отвечающих за взаимодействие между поверхностными и объемными зонами. Проведено сравнение по точности и быстродействию с методом численного интегрирования на примере моделирования теплообмена в экспериментальной печи.</p></abstract><trans-abstract xml:lang="en"><p>A new method based on discrete transfer modeling technique for calculating the direct exchange areas (DEA) in zonal method is presented. The key property of this method is fast DEA matrix evaluation. The computational time was found to be small in comparison to other methods for direct exchange areas evaluations based on numerical quadrature integration. The accuracy of the  procedure is established by comparing the predictions with those based on the numerical integration on test case (IFRF furnace). </p></trans-abstract><kwd-group xml:lang="ru"><kwd>теплообмен излучением</kwd><kwd>зональный метод</kwd><kwd>матрица прямых взаимных поверхностей</kwd><kwd>дискретизация по направлениям</kwd></kwd-group><kwd-group xml:lang="en"><kwd>radiative heat transfer</kwd><kwd>zonal method</kwd><kwd>direct exchanger area matrix</kwd><kwd>discrete transfer modellingmud</kwd><kwd>impact resistance</kwd><kwd>abrasion strength</kwd><kwd>ferrite bond</kwd><kwd>silicate bond</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Modest M.F.
