ABSTRACT
Gas turbine improvement is an immense task that requires significant activ ities in both numerical and experimental combustion research. To meet future emission and efficiency demands, the numerical prediction of gas turbine combustion is growing in importance. For this purpose, computa tional fluid dynamics (CFD) has become a unique tool. A comprehensive CFD model (integral model) consists of various submodels that represent single parts of the whole combustion process as well as the coupling between different phenomena. This chapter presents a survey of different classes of submodels and focuses attention on the respective experimental require ments necessary for submodel development and validation. One selected example of experimentally guided submodel development is presented to more clearly highlight these demands. In addition, a comprehensive data set obtained for a large-scale enclosed swirling flame suitable for integral model validation is shown.
