Résumé : Ablation of an ice bloc by a hot water jet is studied to understand the physical phenomena involved in the process, the final goal is to design SFR’s core-catcher. The system studied is comprised of a water jet and a transparent ice block. Ablation process is followed by use of high-speed camera and back lighting. First results are presented. A new ablation regime is reported. The evolution of ablation speed with time and jet speed is analyzed.
