摘要

A numerical model is presented to analyze the stability of the internally cooled composite superconductors cooled by superfluid helium with phase changes taken into cosideration. To simu- late the unique characteristics of superfluid helium, the momentum difference term between the actual momentum and the homogeneous one is derived, which is added to the conventional Navier-Stokes equation.
