A zero dimensional stability model has been developed for cable-in-conduit superconductors. The model is effective in simulating the multi-valued stability behaviour in the vicinity of the limiting current. This has been by modifying the helium heat transfer coefficient to account for inertial and fractional terms which affect the induced helium flow. Although this effect is treated qualitatively on a pseudo-one-dimensional basis, the model can reproduce with remarkable accuracy the multi-valued stability behaviour shown in earlier measurements performed by Lue, et al. The influence of the steady state mass flow is discussed, and a first order approximation of its effect is introduced in the model showing how an increase of the steady flow tends to wash-away'' the multiple stability region as observed in the experiment.
