Theses and Dissertations
Gas turbines are used in various systems, including in power plants, marine, and aircraft propulsion engines. The airflow in gas turbines can reach temperatures as high as 2000 K that exceeds the softening points for most high-performance blade materials, such as special steels, titanium alloys, and super-alloys. Preventing thermal failure in the turbine-blades has driven many technological advances in materials science and mechanical design. In this thesis, the main focus is on improving the performance of the internal cooling channel technology. In this study, the optimized thermal behavior of the coolant gas and surfaces in turbines by incorporating novel internal …
