The influence of steam's gas-dynamic characteristics to exhaust hood's thermal state at variable rate was detected. With usage of direct conjugate and inverse heat transfer problems the heat-transfer coefficients on inner surfaces of exhaust hood at different rates was calculated. With usage of direct conjugate and inverse heat transfer problems the heat-transfer coefficients on inner surfaces of exhaust hood at different rates was calculated. The possibility of its usage at thermal stress definition was shown. The developed methodology and results of gas-dynamics, thermal and thermal stress investigations can be used at new high efficiency turbines developing which will have advanced reliability at the variable operating conditions Product Description popup.authors Альохіна Світлана Вікторівна Кошель Сергій Васильович Сімбірська Ольга Олександрівна popup.nrat_date 2020-04-02 Close
