  "abstract": "Wall-resolved Large-Eddy Simulation (LES) is assessed in predicting the heat transfer and the flow dynamics within a semi-industrial configuration of a turbine vane cooled by jet impingement. The geometry features 39 jet holes with an average Reynolds number of 10 000 in each hole. Two jet-to-target distances are involved, corresponding to H/D = 6.4 for the leading edge jets and H/D = 2 for the downstream jets impinging a flat plate. In parallel to LES, RANS simulations using the kω Shear Stress Transport (SST) model and the Elliptic Blending Reynolds-Stress Model (EB-RSM) are also performed to provide representative boundary conditions as well as a reference of RANS performance on such a configuration. Numerical results are compared with previously conducted experimental Particle Image Velocimetry (PIV) and infrared (IR) thermography measurements. The overall flow complex topology is discussed and the LES shows a good agreement with PIV. Regarding heat transfer, the kω SST and EB-RSM RANS models exhibit high discrepancies with IR measurements. In contrast, the LES achieves significantly better accuracy. Local heat transfer rates vary with both jet-to-target spacing and mass flow rates. The LES database, validated against experimental measurements, thus offers a reliable reference for turbulence features in multi-jet impingement configurations.",
