Titre : Ablation of ice bloc by a hot water jet – Application to SFR safety Auteurs : Alexandre Lecoanet, Nicolas Rimbert, Michel Gradeck, Frédéric Payot, Revue : Entropy: Thermodynamics – Energy – Environment – Economy Numéro : Issue 4 Volume : 1 Date : 2020/07/7 DOI : 10.21494/ISTE.OP.2020.0519 ISSN : 2634-1476 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. Éditeur : ISTE OpenScience
