Abstract

This study presents a comprehensive numerical investigation into the formation and propagation of rotating detonation waves (RDWs) in hydrogen-air mixtures at cryogenic temperatures, with the objective of evaluating the performance benefits and feasibility of using cryogenic hydrogen in propulsion s...
