We propose a combined experimental and numerical study related to fundamental aspects of blade-cooling flows. We propose to make use of our unique rotating flow facility to produce detailed local flow and heat transfer measurements for impingement-cooling flows over rotating surfaces, curved and plane, and in rotating passages with profiled inclined ribs and with U-bends of variable area. These are flows for which little or no experimental information is currently available. The proposed experiments will thus improve our understanding of these flows and also provide CFD validation data, useful to designers of blade-cooling systems and also to turbulence modellers.On the numerical front, we would first introduce into our general-geometry blade-cooling code non-linear two-equation models and advanced wall-functions, both of which are currently being developed in our group. These and other models of turbulence already included in our code, zonal and low-Re EVM and differential stress models, will then be assessed in computations of some of the flows examined in our experimental investigations. Moreover, computations of cooling flows through passages with profiled ribs and variable area u-bends, will then help us to determine the optimum geometries, which will be tested experimentally.
