A numerical study is presented, using the SOLPS-ITER plasma boundary code with full drifts and currents activated, of impurity seeded JET discharges in support of high power H-mode experimental campaigns designed to compare two ITER candidate seeding species, nitrogen (N) and neon (Ne). Fluid-kinetic edge plasma simulations are first performed at lower levels of power into the scrape-off layer (SOL) and benchmarked against existing JET experimental data. Calculations are then performed for higher levels of SOL power to examine the impact of this key parameter on the efficiency of both radiators. From the code point of view, for the chosen JET parameters, Ne can be as efficient a divertor radiator as N at the same level of upstream separatrix Zeff

A three-dimensional feature-based jet model is proposed for the numerical simulation of film cooling flows. The modelling is made in the near hole region and model coefficients are experimentally anchored. The model previously validated for streamwise jet injection cases is modified so that compound jet injection can be simulated. The modifications of the model concern the lateral trajectory of the jet and the structural change of the coolant Counter-rotating Vortex Pair (CVP). It is shown that the modelling strategy is relevant and robust for moderate compound angle injection and that higher injection angle necessitates deeper structural change of the modelling approach.
