Г. Пенязьковым</p><p>Методом крупных вихрей (LES) с использованием пакета OpenFOAM (Open Field Operation and Manipulation) выполнен расчет и анализ средней скорости, пульсаций, пространственных корреляций пульсаций скорости и волновых спектров пульсаций компонент скорости в развитом трехмерном турбулентном пограничном слое. Пограничный слой формировался при течении воды со средней скоростью 0,3 м/с в плоском канале размерами 50 х 125 х 850 мм (высота, ширина и длина соответственно). Скорость на входе в канал задавалась по закону 1/7. Число Рейнольдса, рассчитанное по половине высоты канала, равнялось 7500. Расчеты выполнены на двух координатах y+ = 10 и 40, т. е. в буферной и логарифмической областях пограничного слоя. Исследования показали, что в буферной области формируются вихревые структуры, которые сохраняют свою идентификацию и в начале логарифмической области (y+ = 40). Эти структуры формируют пакеты из вихрей различного масштаба. Размер этих пакетов в поперечном сечении существенно меньше, чем их длина. Дискретные пакеты слабо взаимодействуют между собой поперек пограничного слоя, что проявляется в постоянстве энергетического спектра в широком интервале волновых чисел.</p></abstract><trans-abstract xml:lang="en"><p>Communicated by Academician Oleg G. Penyazkov</p><p>Mean velocity, fluctuations, spatial correlations and wave number spectra were calculated and analyzed by the LES method using the software OpenFOAM for solution of the task of the developed 3D turbulent boundary layer. The layer was formed in water flowing in the 50 х 125 х 850 mm flat channel (height, width and length, respectively) at a mean entrance velocity of 0.3 m/s that results in the Reynolds number based on the half channel height equal to 7500. The velocity profile at the channel entrance was set by the law 1/7. The turbulent parameters were calculated on two coordinates: y+ = 10 and 40, i. e. in the buffer and logarithmic regions of the boundary layer. The study showed that the vortex structures were generated in the buffer region; they were still identified at the beginning of the logarithmic region (y+ = 40). These structures form vortex packets whose scale in the transverse direction is much less than their length. The vortex packets weakly interact with each other in the transverse direction, which results in an almost constancy of the energy spectrum within a broad wave number range.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>пограничный слой</kwd><kwd>пульсации</kwd><kwd>корреляции пульсаций</kwd><kwd>спектры пульсаций</kwd></kwd-group><kwd-group xml:lang="en"><kwd>turbulent boundary layer</kwd><kwd>LES</kwd><kwd>spatial correlation</kwd><kwd>wave number spectra</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке Белорусского фонда фундаментальных исследований (грант Т18Р-018) и Российского фонда фундаментальных исследований (грант 18-58-00011)</funding-statement><funding-statement xml:lang="en">The work was sponsored by the Belarusian Republican Foundation for Fundamental Research (grant Т18Р-018) and the Russian Foundation for Fundamental Research (grant 18-58-00011)</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">Zhou, J.
