Effect of purge air on rotor endwall heat transfer of an axial turbine

Effect of purge air on rotor endwall heat transfer of an axial turbine

In order to gain in cycle efficiency, turbine inlet temperatures tend to rise, posing the challenge for designers to cool components more effectively. Purge flow injection through the rim seal is regularly used in gas turbines to limit the ingestion of hot air in the cavities and prevent overheating...
