Identification of heat transfer coefficients on surfaces of exhaust hood of steam turbine
An investigations of thermal and gas dynamics processes have been carried out for thermal stress estimation in steam turbine exhaust hood. The direct coupled problem of heat exchange has been solved. Based on these results the heat transfer coefficients on surfaces by the decision of inverse problem...

Для оценки термонапряженного состояния выходного патрубка цилиндра высокого давления паровой турбины проведены исследования тепловых и газодинамических процессов. Решена прямая сопряженная задача теплообмена. Базируясь на этих результатах, определены коэффициенты теплоотдачи на поверхностях патрубка путем решения обратной задачи теплообмена. Данные могут быть использованы для оценки ресурса работы паровых турбин. Для оцінки термонапруженого стану вихідного патрубка циліндра високого тиску парової турбіни проведені дослідження теплових та газодинамічних процесів. Розв’язана пряма спряжена задача теплообміну. Базуючись на цих результатах, визначені коефіцієнти тепловіддачі на поверхнях патрубка шляхом розв’язання оберненої задачі теплообміну. Дані можуть бути використані для оцінки ресурсу роботи парових турбін.
