Cross-scale mechanistic investigation of multistage carbon dioxide pool flash evaporation with vertical heterogeneity

Pool flash evaporation is a canonical liquid–vapor phase-change process driven by rapid depressurization, yet the stage-dependent flow-pattern evolution and vertical thermodynamic heterogeneity remain poorly understood. Existing heat and mass transfer models treat the process as...

Investigation of the heat transfer of supercritical carbon dioxide in a vertical tube under high-temperature and high-pressure conditions

The design and refinement of the supercritical carbon dioxide (S-CO 2 ) direct cycle nuclear energy system are crucial for advancing the application of green energy and mitigating the energy crisis. The key to this lies in the research on the heat transfer characteristics of S-CO...
