ShareNatural convection in large helium II baths.
Author(s) : RAMADAN N. H., WITT R. J.
Type of article: Article
Summary
In superconducting magnetic energy storage systems the postulated design includes baths 20 m high housing superconductive coils. In the paper the circulation velocity resulting from the natural convection process is evaluated. The equations are formulated using a single-fluid model and a two-fluid model, which describe helium II as consisting of two interpenetrating fluids, the normal and superfluid. Results indicate that natural convection cells in superfluid helium evolve in a fundamentally different way than those in ordinary fluids, because of the counterflow that develops in the presence of temperature gradients.
