... with rising temperature due to the gaseous CO 2 in the submerged environment, resulting in reduced resistance. The erosion effect is influenced by the characteristics of the jet. At 2.5-5MPa, the CO 2 in the submerged environment undergoes a phase transition from gaseous to liquid. At 5-10MPa, the erosion...
