摘要：To achieve higher thermal efficiency and specific power of modern gas turbines, increasing turbine inlet temperature becomes imperative. Turbine vane is operating in an extreme environment which leads to big challenges for vane cooling including: high hot gas temperature, high mainstream turbulence, randomness, cooling air limit, low-pressure head and mechanical load. A review of flow and heat transfer field inside and outside turbine vane is given. From a designer point of view, discussion of the challenges in vane cooling design and possible ways to meet those challenges is presented. Summarized design experiences and manufacturability in vane cooling design as well as design approaches and examples are discussed. Step by step guidelines in design procedures and thermal analysis are provided.
