The HB-2 numerical simulation results for Mach from 1.5 to 3 under angle of attack from –2 deg to +24 deg are presented. The comparison between computational and experimental [Vuković D., Damljanović D. 2019] data is performed. The calculations were conducted us-ing the method for splitting into the physical processes which uses the unstructured grids. The comparison between hexahedron and prismatic grids is demonstrated.

Расчетное исследование аэродинамики стандартной модели HB-2 при сверхзвуковых скоростях

В данной статье представлены результаты расчетов обтекания стандартной модели HB-2 для условий набегающего потока, соответствующим числам Маха от 1.5 до 3 в диапазоне углов атаки от –2…+24 градусов. Выполнено сравнение результатов расчетов с опубликованными экспериментальными данными [Vuković D., Damljanović D. 2019] по силовым и моментным характеристикам. Цикл расчетов был выполнен с применением метода расщепления по физическим процессам, реализованного на неструктурированных сетках. Показано сравнение результатов расчетов, полученных на гексагональных и призматических сетках.
