Computational Modeling of Tip Heat Transfer to a Superscale Model of an Unshrouded Gas Turbine Blade
This paper compared highly detailed measurements of flow and heat transfer in the tip region of a gas turbine blade with the results of CFD simulations. The research provided guidance on tip gap leakage flow and heat transfer modelling at a computational cost acceptable to engine designers but with adequate resolution to capture real changes in the flow structure. Moving and stationary casing walls were successfully represented, both experimentally and using CFD, and the results prompted the use of stationary wall experiments in subsequent programmes including SAMULET (£1.2M from EPSRC -EP/G035245).
