✦ Synopsis
In relation to the refrigeration of rotating superconducting machinery, solutions are given for the compressible flow of helium in thermally conducting ducts which are rotating about an axis perpendicular to their length. If the flow were isentropic, centrifugal compression would cause the temperature of the helium to rise to unacceptable values: flow in a duct with thermally conducting walls will reduce this temperature rise, Practical considerations are examined for using such a thermal shunt made of copper to produce substantial reductions in this temperature rise.
