Infrared Assessment of Overall Effectiveness of a Modern Turbine Vane Cooling Scheme
46th AIAA/ASME/SAE/ASEE Joint Propulsion Conference & Exhibit, 2010An experimental approach is used to evaluate a baseline vane airfoil cooling configuration for advanced gas turbine engine application by incorporating arrays of two types of cooling holes at prescribed angles, spacing and sizes into large-scale flat plate specimens.

Overall Effectiveness of a Blade Endwall With Jet Impingement and Film Cooling
Journal of Engineering for Gas Turbines and Power, 2013Ever-increasing thermal loads on gas turbine components require improved cooling schemes to extend component life. Engine designers often rely on multiple thermal protection techniques, including internal cooling and external film cooling. A conjugate heat transfer model for the endwall of a seven-blade cascade was developed to examine the impact of ...

Volume 4: Heat Transfer, Parts A and B, 2012
The overall cooling effectiveness for a turbine airfoil was quantified based on the external surface temperature relative to the mainstream temperature and the inlet coolant temperature. This can be determined experimentally when the model is constructed so that the Biot number is similar to that of engine components. In this study, the overall cooling

The laminated cooling or the layered cooling configuration with integrated impingement, rib-roughed and film cooling can result in a high overall cooling effectiveness and is believed to be a promising cooling technology for the next generation of advanced gas turbines. Previous studies found that the relative locations among the film hole, impingement
