TY - CPAPER AB - The Internal Cooling Air Systems for Gas Turbines (ICAS-GT)research programme, sponsored by the European Commission, ranfrom January 1998 to December 2000, and was undertaken by aconsortium of ten gas turbine manufacturing companies and fouruniversities. Research was concentrated in five discrete but relatedareas of the air system including turbine rim seals, rotating cavityflow and heat transfer, and turbine pre-swirl system effectiveness. Ineach case, experiments were conducted to extend the database ofpressure, temperature, flow and heat transfer measurements toengine representative non-dimensional conditions. The data wasused to develop correlations, and to validate CFD and FEcalculation methods, for internal fluid flow and heat transfer.This paper summarises the outcome of the project bypresenting a sample of experimental results from each technicalwork package. Examples of the associated CFD calculations areincluded to illustrate the progress made in developing validatedtools for predicting rotating cavity flow and heat transfer over anengine representative range of flow conditions.
