The High Efficiency Thermal Shield (HETS) concept was proposed by ENEA for divertor application in the context of the ITER project and as part of the European Power Plant Conceptual Study. The design is modular, and the unit dimensions are of the order of centimeters for limiting mechanical and thermal stresses. This paper presents results of thermal-fluid and structural analyses, with different heat flux loads, fluid pressures and inlet velocities. The fluid analysis shows that the sharp corner flow passage at the point of flow reversal behaves like an abrupt enlargement, leading to considerable pressure losses as compared to the results obtained by rounding the corner. The combination of rounding the sharp corner and flow cross-sectional area expansion, leads to reduced pressure losses, without any degradation of the thermal performance of the component.
