Within the framework of safety studies, it is necessary to have validated models of the fluid forces exerted on fuel assemblies in the event of an earthquake. In the PWR (Pressurized Water Reactor) technology used in France, fuel assemblies are made of cylindrical rods bundles arranged in a square array and subjected to an axial flow. In case of an earthquake, these assemblies are subjected to lateral oscillations. These vibrations can lead to the deformation of the assemblies. Test campaigns on real fuel assemblies have been carried out and have revealed the existence of dissipative fluid forces whose evolution and spatial distribution are still poorly documented. The objective of the present work is to contribute to the description of the...
