Abstract: High temperature superconducting (HTS) cables employed in futuristic power stations, fusion engineering and research realm, are scrutinized in the prevailing study. Internally cooled by cryogenic fluids (here liquid nitrogen - LN2) based on YBCO or BSSCO superconducting materials (due to their commercial viability), HTS cables are capable of handling extensive current load, with no heating loss (below their critical temperatures). In the present work, the flow dynamics of LN2 is studied, inside a corrugated pipe, to characterize and comprehend the mechanism of enhanced heat transfer, which would lead to an optimum design of such new generation cables. Maintaining the operating conditions of the superconducting tapes is the prime objective of forced-flow LN2, which has perplexing and intricate flow nature. |
