Heat Transfer in Turbine Hub Cavities Adjacent to the Main Gas Path

Abstract: Reliable means of predicting heat transfer in cavities adjacent to the main gas path are increasingly being sought by engineers involved in the design of gas turbines. In this paper, an interim summary of the results of a five-year research program sponsored by the European Union (EU) and several leading gas turbine manufacturers and universities will be presented. Extensive use is made of computational fluid dynamics (CFD) and finite element (FE) modeling techniques to understand the thermo-mechanical behavio… Show more

“…These modelling capabilities have been validated using measured data from the two-stage turbine facility sited at the University of Sussex. Both steady and unsteady CFD solutions have been produced during the project, some presented at previous ASME conferences [5] and [6], with comparisons to measured data. Alternative cooling configurations have been both modelled and tested for a range of cooling flow levels.…”
