More accurate agreement of the numerical results and experimental data for a number of flow passages of steam turbines are presented. An implicit splitting scheme for the conservation laws numerical integration on unstructured grids, as well as an approach to the construction of reconstruction with arbitrary order of accuracy and a method to minimize its coefficients, are proposed. Numerical testing of the proposed approaches on a number of model problems of fluid dynamics confirmed that the methods provide the desired order of accuracy for smooth solutions and are of sufficient computational efficiency. It is expected, that in the future the executed developments will be introduced on all new power steam turbines. It is expected that future developments of new power installation will be used to create new high-power installations Product Description popup.authors Агібалов Євген Сергійович Городецький Юрій Володимирович Дєдков Валерій Миколайович Депарма Галина Олексіївна Заїка Володимир Миколайович Калєнько Тетяна Олександрівна Косьянов Дмитро Юрійович Косьянова Анна Ігорівна Крамський Олександр Володимирович Пащенко Наталя Вікторівна Русанов Андрій Вікторович Сухоребрий Петро Миколайович Ткачик Олена Миколаеївна Хорєв Олег Миколайович Шелудяков Леонід Олегович popup.nrat_date 2020-04-02 Close
