Предложен оригинальный алгоритм моделирования генерации замкнутых петель на поверхности обтекаемого тела и их эволюции в потоке. Обсуждаются результаты тестирования алгоритма на задачах обтекания сферы и цилиндра. Показано, что полученные в расчете распределения давления по поверхности тел удовлетворительно согласуются с известными экспериментальными данными.</p></abstract><trans-abstract xml:lang="en"><p>New modification of the vortex element method which uses closed vortex loop to calculate the incompressible 3D-flow around bodies by flow of an incompressible medium and determining the unsteady hydrodynamic loads is considered. An original algorithm for closed loops generation on the surface of the body simulation and their evolution in the stream is proposed. The results of algorithm tests is discussed. The model problems of the flow around sphere and cylinder is investigated. It is shown that the results obtained in the pressure distribution on the body surface calculation are in good agreement with the experimental data.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>вихревые нити</kwd><kwd>метод вихревых элементов</kwd><kwd>вычислительная гидродинамика</kwd><kwd>обтекание тел</kwd><kwd>поток несжимаемой среды</kwd></kwd-group><kwd-group xml:lang="en"><kwd>vortex filaments</kwd><kwd>vortex element method</kwd><kwd>computational fluid dynamic</kwd><kwd>flow around bodies</kwd><kwd>incompressible flow</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">Трехмерное отрывное обтекание тел произвольной формы / под ред.
