Film Cooling With Wake Passing Applied To An Annular Endwall, Nghia Trong Tran Jan 2010

Film Cooling With Wake Passing Applied To An Annular Endwall, Nghia Trong Tran

Electronic Theses and Dissertations

Advancement in turbine technology has far reaching effects on today's society and environment. With more than 90% of electricity and 100% of commercial air transport being produced by the usage of gas turbine, any advancement in turbine technology can have an impact on fuel used, pollutants and carbon dioxide emitted to the environment. Within the turbine engine, fully understanding film cooling is critical to reliability of a turbine engine. Film cooling is an efficient way to protect the engine surface from the extremely hot incoming gas, which is at a temperature much higher than allowable temperature of even the most …


Interaction Between Secondary Flow & Film Cooling Jets Of A Realistic Annular Airfoil Cascade (High Mach Number), Cuong Quoc Nguyen Jan 2010

Interaction Between Secondary Flow & Film Cooling Jets Of A Realistic Annular Airfoil Cascade (High Mach Number), Cuong Quoc Nguyen

Electronic Theses and Dissertations

Film cooling is investigated on a flat plate both numerically and experimentally. Conical shaped film hole are investigated extensively and contribute to the current literature data, which is extremely rare in the open public domain. Both configuration of the cylindrical film holes, with and without a trench, are investigated in detail. Design of experiment technique was performed to find an optimum combination of both geometrical and fluid parameters to achieve the best film cooling performance. From this part of the study, it shows that film cooling performance can be enhanced up to 250% with the trenched film cooling versus non-trenched …
