Note:
Fluids under supercritical (SC) conditions have the potential to enhance thermal transport from ultra-high heat flux surfaces and facilitate exceedingly-effective thermal control and management of devices/ systems, including heat exchangers that may be of industry-scale, additively-manufactured, and/or microchanneled, either passive (closed system without a pump, buoyancy-induced flow) or active (in a pumped flow loop). SC fluids can soon find applications in direct solar energy conversion; cooling of electronics, avionics, laser, and biomedical devices; and thermal management of server rooms, large data storage systems, and high-power rechargeable batteries. Their future thermal applications may also include thermal power plants, including nuclear; geothermal energy systems; refrigeration/cryogenic systems (even below -100°C); space shuttles, satellites, and space station; lunar surface system; carbon capture and storage (CCS); cooling of superconducting transmission cables; and fusion energy systems, to name a few. However, research on SC heat transfer has been limited because of (a) the inadequate experimental data as well as the lack of scientific understanding of SC fluids, (b) anomalous behavior, characterized by largescale variations in thermophysical properties in a region around the critical point (CP), (c) thermal oscillations and fluctuations near the critical point (CP), and (d) possibility of deteriorated heat transfer.
