Основной целью исследования является оценка эффективности метода штрафных функций, также известного как метод погруженной границы, для решения задач сжимаемой газовой динамики. Применяется модифицированные уравнения Навье-Стокса с учетом обтекаемых тел и используют схему ENO для численного решения. Результаты моделирования демонстрируют, что предложенный подход успешно описывает физические процессы, происходящие при сверхзвуковом обтекании конуса и сферы, включая формирование ударных волн, распределение давления, температуры и плотности. Полученные данные сравниваются с экспериментальными результатами, подтверждая адекватность и точность разработанной численной модели. Представленная работа вносит вклад в развитие методов численного моделирования сжимаемых сверхзвуковых течений и демонстрирует перспективность использования метода штрафных функций для решения широкого класса задач газовой динамики.</p></abstract><trans-abstract xml:lang="en"><p>This paper deals with numerical modelling of supersonic flow of cone and sphere bodies using the penalty function method. The main objective of the study is to evaluate the effectiveness of the penalty function method, also known as the immersed boundary method, for solving compressible gas dynamics problems. We apply modified Navier-Stokes equations considering streamlined bodies and use the ENO scheme for the numerical solution. The simulation results demonstrate that the proposed approach successfully describes the physical processes occurring in the supersonic flow of a cone and sphere, including the formation of shock waves, pressure, temperature and density distributions. The obtained data are compared with experimental results, confirming the adequacy and accuracy of the developed numerical model. The presented work contributes to the development of methods for numerical modelling of compressible supersonic flows and demonstrates the promising use of the penalty function method for solving a wide class of gas dynamics problems.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>обтекание конуса</kwd><kwd>обтекание сферы</kwd><kwd>сверхзвуковой поток</kwd><kwd>турбулентное течение</kwd><kwd>сжимаемый газ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>flow past a cone</kwd><kwd>flow past a sphere</kwd><kwd>supersonic flow</kwd><kwd>turbulent flow</kwd><kwd>compressed gas</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">Mittal R. and Iaccarino G.
