ЦЕЛЬ. Изучить гидро-аэродинамические свойства потоков, проходящих через пористые вставки на основе топологий трижды периодических минимальных поверхностей (ТПМП). Разработать методику исследования пористых материалов с упорядоченной пространственной структурой. Определить потенциально пригодные для применения в теплообменном оборудовании пористые материалы на основе ТПМП. МЕТОДЫ. При решении поставленных задач были использованы численные (CFD) и экспериментальные методы. Для численного моделирования использовалось программное обеспечение Ansys Fluent 2019 R3. Опытные образцы для натурного эксперимента, проводимого на лабораторной установке ВЕНТ-08-7ЛР-01, были изготовлены при помощи аддитивных технологий SLA. Пористость образцов вирировалась от 0,73 до 0,89. Эксперимент проводился при скорости на входе в трубку от 0.3 до 4,5 м/с. РЕЗУЛЬТАТЫ. По результатам исследования получены новые эмпирические зависимости потерь давления от скорости потока для вставок на основе поверхностей: Primitive (P), Fischer Koch S (FKS), Neovius (N), Schoen's I-WP (IWP). Воздушный поток при прохождении через структуру N демонстрировал наибольшие потери давления, в то время как через структуру P потери при той же скорости были меньше в 8 раз. В пористых вставках выявлены застойные области, которые могут оказывать отрицательное воздействие на теплопередачу. Определены изменения локальной скорости потока в пористых вставках, коррелирующие с просветностью вставки. ЗАКЛЮЧЕНИЕ. Результаты исследования могут быть использованы для проектирования систем охлаждения с оребрением на основе ТПМП. Исходя из проведенного анализа распределения векторного поля скоростей и потерь давления, структуры FKS и IWP могут потенциально быть использованы в теплообменном оборудовании.</p></abstract><trans-abstract xml:lang="en"><p>RELEVANCE: The relevance of this work lies in the study of new porous materials for use in compact, highly efficient heat exchange devices. PURPOSE: To investigate the hydro-aerodynamic properties of flows passing through porous inserts based on triply periodic minimal surface (TPMS) topologies. To develop a methodology for studying porous materials with ordered structures. To identify potentially suitable TPMS-based porous materials for application in heat exchange equipment. METHODS: Numerical (CFD) and experimental methods were used to address the research objectives. Ansys Fluent 2019 R3 software was utilized for numerical modeling. Experimental samples for the physical experiments conducted on the VENT-08-7LR-01 laboratory setup were fabricated using SLA additive technologies. The porosity of the samples ranged from 0.73 to 0.89. The experiment was conducted with inlet velocities ranging from 0.3 to 4.5 m/s. RESULTS: New empirical dependencies of pressure drop on flow velocity were obtained for inserts based on the surfaces: Primitive (P), Fischer Koch S (FKS), Neovius (N), and Schoen's I-WP (IWP). The airflow through the N structure showed the highest pressure drop, while the P structure had 8 times less pressure drop at the same velocity. Stagnation zones, which can negatively impact heat transfer, were identified in the porous inserts. Changes in local flow velocity in the porous inserts were determined to correlate with the insert's transparency. CONCLUSION: The research results can be used for designing cooling systems with TPMS-based ribbing. Based on the analysis of the velocity vector field distribution and pressure drops, the FKS and IWP structures have potential applications in heat exchange equipment.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>потери давления</kwd><kwd>пористый материал</kwd><kwd>оребрение</kwd><kwd>Primitive</kwd><kwd>Fischer Koch S</kwd><kwd>Neovius</kwd><kwd>Schoen's I-WP</kwd><kwd>трижды периодические минимальные поверхности</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Pressure Drop</kwd><kwd>Porous Material</kwd><kwd>Ribbing</kwd><kwd>Primitive</kwd><kwd>Fischer Koch S</kwd><kwd>Neovius</kwd><kwd>Schoen's I-WP</kwd><kwd>Triply periodic minimal surface</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено за счет гранта Российского научного фонда №23-79-10044, rscf.ru/project/23-79-10044/.</funding-statement><funding-statement xml:lang="en">This work is supported by the Russian Science Foundation under grant 23-79-10044, rscf.ru/project/23-79-10044/.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Gürel B. et al.
