“…Georgiev and Kovatchev 56 developed a new type of multichannel low-temperature heat exchanger based on helical coiled tubes, which is mainly designed for liquefiers and refrigerators with small and average capacity. The application of coiled tube heat exchangers have been reported by Sheft et al in the Argonne hydrogen conversion and storage system (HYCSOS), which is a two-hydride concept that operates as a chemical heat pump for the storage and recovery of thermal energy for heating, cooling, and energy conversion. Prasad et al tested the performance of the coiled tube heat exchanger as a waste heat recovery device for a 60 HP gas turbine and found excellent corroboration of the effectiveness−NTU relation between their simulation results with in situ experiments.…”

The potential industrial applications of curved tubes for single- and two-phase flow are reviewed within the context of physics of flow, trends in the development of technology, and its laboratory to industrial-scale commercialization. Comparison of the performance of curved tube configurations demonstrates its edge over the conventional motionless mixers, heat exchangers, and reactors. Alongside, their respective advantages and limitations are also highlighted. Further, a compendium of the available correlations for single- and two-phase friction factor and heat- and mass-transfer coefficient in curved tubes has also been presented. Key issues regarding the design parameters governing the performance of the curved tubes for mixing and heat- and mass-transfer that impact the research, development, and scale-up or scale-down of such devices are also analyzed. Emerging trends for the development of a new class of curved tubes, namely, inverters and serpentine and chaotic devices are also presented.

“…Although not rare-earth based, under more moderate conditions of temperature and pressure, the CaNi 5 system displays a loss of RHC [4,[6][7][8] that is much more rapid than the LaNi 5 system. Loss of RHC during the storage of CaNi 5 H x at various temperatures is reported in [9].…”
