Приводятся решения ряда модельных задач (течение в слое смешения, течение в дозвуковой неизотермической турбулентной струе, истекающей из круглого сопла в затопленное пространство, аэрооптические эффекты в турбулентных потоках). Результаты расчетов сравниваются с данными, полученными на основе решения осреденных по Рейнольдсу уравнений Навье-Стокса и уравнений k - ε модели турбулентности, а также с имеющимися данными физического эксперимента. Делаются выводы о перспективах использования данного подхода в задачах гидрофизики и гидроакустики.</p></abstract><trans-abstract xml:lang="en"><p>Applications of large-eddy simulation (LES) technique to the solution of problems of hydrophysics and hydroacoustics are considered. Solutions of some model problems (free mixing layer, free sub-sonic nonisothermal turbulent jet flowing out of circular nozzle into submerged space, and aero-optical effects in turbulent flows) are presented. The results obtained are compared to the data calculated with the numerical solution of the Reynolds-averaged Navier–Stokes equations and equations of the k–ε turbulence model, as well as to the available experimental data. The conclusions related to the perspectives of use of this technique in the problems of hydrophysics and hydroacoustics are made.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>турбулентность</kwd><kwd>моделирование крупных вихрей</kwd><kwd>расчет течений жидкости</kwd><kwd>струя</kwd><kwd>слой смешения</kwd></kwd-group><kwd-group xml:lang="en"><kwd>turbulence</kwd><kwd>large-eddy simulation</kwd><kwd>computational fluid dynamics</kwd><kwd>jet</kwd><kwd>mixing layer</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">Корчагин Н.Н., Монин А.С.
