Three dimensional calculation of double cone 25°/55° aerothermodynamics using a family of computer codes UST3D

A numerical modeling of the three dimensional flow around a 25°/55° double cone
by a high-velocity gas flow on an unstructured grid is carried out. Numerical simulation
was carried out in N2 (nitrogen) gas. For numerical simulation, the author's computer codes UST3D-AUSMUP2, UST3D-AUSMPW and USTFEN, developed at IPMech RAS,
were used. These computer codes are based on the model of the complete system
of Navier Stokes equations for a perfect gas, which is solved by different methods
on an unstructured grid. Validation and verification of the obtained results were carried out. For numerical simulation of the flow, a geometric model of a double cone 25°/55°
was constructed.

Пространственный расчет аэротермодинамики двойного конуса 25°/55° с помощью семейства компьютерных кодов UST3D

Выполнено численное моделирование пространственного обтекания двойного конуса 25°/55° высокоскоростным потоком газа на неструктурированной сетке. Численное моделирование проводилось в газе N2 (азот). Для численного моделирования использовались авторские компьютерные коды UST3D-AUSMUP2, UST3D-AUSMPW, а также USTFEN, разработанный в ИПМех РАН. В основе данных компьютерных кодов лежит модель полной системы уравнений Навье-Стокса совершенного газа, решаемая различными методами на неструктурированной сетке. Проведены валидация и верификация полученных результатов. Для численного моделирования обтекания была построена геометрическая модель двойного конуса 25°/55°.
