Kurzfassung
This paper presents an efficient multifidelity process for the design and analysis of cooled axial flow turbine components. The process is initiated with data from a 0D performance model. First, a 1D meanline method is used to define the general turbine layout and the cooling requirements. Then, the blade profile geometry and the boundary conditions for a cooling design method are generated using 2D through-flow and passage flow simulations. Finally, the 3D blade and internal cooling geometry are analyzed using 3D computational fluid dynamics (CFD) simulations. The process is applied to a nozzle guide vane of a next-generation turbofan engine, and the resulting data is compared and evaluated. This approach provides an efficient and effective means of validating novel engine concepts by refining and assessing turbine components in a timely manner.
