Abstract:It is known that progress in the development of superconducting energy transmission lines is hampered by the complexity of cooling of the superconducting cable since refrigerant (usually liquid nitrogen) is pumped through the very long and narrow cryogenic channels. In this report, we consider the possibility of increasing the pumping length of liquefied gases by reducing the hydraulic resistance of the cryogenic channels.
