2. On Film Cooling of Turbine Guide Vanes : From Experiments and CFD-Simulations to Correlation Development
Sammanfattning : To achieve high thermal efficiency in modern gas turbines, the turbine-inlet temperature has to be increased. In response to such requisites and to prevent thermal failure of the components exposed to hot gas streams, the use of different cooling techniques, including film cooling, is essential. LÄS MER
