Метод штрафных функций особенно эффективен при использовании ортогональных структурных сеток в рамках схемы конечных разностей и широко применяется для решения задач как ламинарного, так и турбулентного течения. Метод основан на прямом применении уравнений Навье-Стокса с добавленными источниками, что позволяет задавать граничные условия косвенным образом. Этот метод облегчает наложение граничных условий Дирихле, но усложняет применение условий Неймана. Тем не менее метод хорошо работает с обоими типами граничных условий, что делает его подходящим для тепловых и сжимаемых потоков, где часто используются условия Неймана. Несмотря на свою гибкость, метод требует высокой степени управления данными и дополнительного кодирования. В данной работе представлены результаты недавно разработанного метода более высокого порядка для сжимаемых дозвуковых потоков, демонстрирующие точное моделирование движущихся объектов без численного шума. Метод был протестирован на стационарных и движущихся  объектах в широком диапазоне чисел Рейнольдса и Маха.</p></abstract><trans-abstract xml:lang="en"><p>Numerical modelling of compressible flows around moving solids is important for engineering applications such as aerodynamic flutter, rocket engines and landing gear. The penalty function method is particularly effective when using orthogonal structural meshes within a finite difference scheme and is widely used to solve both laminar and turbulent flow problems. The method is based on the direct application of the Navier-Stokes equations with added sources, which allows the boundary conditions to be set indirectly. This method facilitates the imposition of Dirichlet boundary conditions but complicates the application of Neumann conditions. Nevertheless, the method works well with both types of boundary conditions, making it suitable for thermal and compressible flows where Neumann conditions are often used. Despite its flexibility, the method requires a high degree of data management and additional coding. This paper presents results of a recently developed higher-order method for compressible subsonic flows, demonstrating accurate modeling of moving objects without numerical noise. The method has been tested on stationary and moving objects over a wide range of Reynolds and Mach numbers.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>численное моделирование</kwd><kwd>цилиндр</kwd><kwd>дозвуковое течение</kwd><kwd>метод штрафных функций</kwd><kwd>система уравнений Навье-Стокса</kwd></kwd-group><kwd-group xml:lang="en"><kwd>numerical modelling</kwd><kwd>cylinder</kwd><kwd>subsonic flow</kwd><kwd>penalty function method</kwd><kwd>Navier-Stokes equations system</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">Engels T., Kolomenskiy D., Schneider K., Sesterhenn J.
