Корректировка модели турбулентности для определения коэффициента сопротивления осесимметричной модели с лодочной хвостовой частью на транс- и сверхзвуковых скоростях

Для повышения точности численных результатов по определению коэффициента сопротивления осесимметричной модели с лодочной хвостовой частью на сверхзвуковых скоростях выполнена корректировка модели турбулентности k–? SST. Численный метод модифицирован путем уточнения параметров модели турбулентности: a1 и ?* для различных значений числа Маха. Скорректированная модель турбулентности k–? SST позволяет снизить погрешность численных результатов на 0.06…0.18 % по сравнению с экспериментальными данными при числе Маха 1.2…2.5. Результаты подтверждены для 130-миллиметровой модели снаряда.
