Description
The storage and generation of power has been a main objective over the past decade. To accomplish such an objective, superconductors are introduced in 1978, which observed a sublime growth in power generation systems. However, electrical losses such as AC losses and thermal losses due to conduction, convection and radiation in those superconductors are inevitable. In order to overcome and reduce these losses, use of cryogenic fluids above their critical temperature is necessary. One such fluid being studied in this work is supercritical hydrogen (SCH). Various thermophysical properties such as density, viscosity, thermal conductivity and specific heat of SCH were studied. The results reveal that with the rise in temperature there is a radical change in thermophysical properties of SCH. Besides, few correlations have been developed for the same at various pressures and temperatures. The developed correlations are elaborated such that, the use of supercritical hydrogen (SCH) may be explored in the HTS generator for improving its performance. These correlations can be employed for further research and advancement in HTS generators. Due to the dynamic nature of HTS generators, unlike HTS cables, the cooling requires careful attention and precise monitoring. With the use of SCH, a uniform temperature distribution in HTS generators is expected leading to higher efficiency.
