Проведено численное исследование течения газа через высокопористый ячеистый материал с твердотельными перегородками и перегородками, содержащими микропоры. Оценено воздействие изменения геометрии посредством добавления микропор на перепад давления, эффективность осаждения частиц и коэффициент качества фильтра. Результаты показали, что добавление микропор положительно влияет на фильтрующие и гидродинамические свойства высокопористого материала для той же макропористости среды, а для случая суммарной пористости среды материал с микропорами позволяет получить повышенное значение эффективности осаждения и коэффициента качества фильтра для частиц малого размера.

In this work we carried out a numerical study of the gas flow through an open cell foam material with solid-state partitions and partitions containing micropores. The effect of a geometry change by adding micropores on the pressure drop, particle deposition efficiency, and filter quality factor is estimated. The results showed that the addition of micropores positively affects the filtering and hydrodynamic properties of the highly porous material for the same macroporosity of the medium, and for the case of total porosity of the medium, the material with micropores allows one to obtain an increased value of the deposition efficiency and filter quality factor for small particles.
