Jet Impingement Cooling Configurations For Gas Turbine Combustion, Eric Ian Esposito
Jet Impingement Cooling Configurations For Gas Turbine Combustion, Eric Ian Esposito
LSU Master's Theses
Impinging jets are commonly used to enhance heat transfer in modern gas turbine engines. Impinging jets used in turbine blade cooling typically operate at lower Reynolds numbers in the range of 10,000 to 20,000. In combustor liner cooling, the Reynolds numbers of the jets can be as high as 60,000. The present study is aimed at experimentally testing two different styles of jet impingement geometries to be used in backside combustor cooling. The higher jet Reynolds numbers lead to increased overall heat transfer characteristics, but also an increase in crossflow caused from spent air. The crossflow air has the effect …
