Research on active modulation of gas turbine cooling air flow
Applied Thermal Engineering(2023)
摘要
•Firstly proposing “active coolant modulation” to improve engine efficiency.•A gas turbine model for active cooling air modulation study is first established.•An analytical blade cooling model is established.•First-time distinction of blade pressure and suction surfaces' hot gas parameters.•Firstly proposing “equivalent air-film coverage” concept and optimizing it by GAs.
