| Popis: | We present a theoretical model which describes the thermal expansion of one or two normal phases along a current-carrying type-I inhomogeneous superconducting wire. We derive explicit formulas for the longitudinal propagation velocity in the case of low regimes using a quasi-stationary approximation of the heat equation, as well as for the onset of thermal destruction of superconductivity. In the case of two normal phases propagating in opposite directions, the model predicts a yet unobserved thermal interaction at distances d of the order of the diameter of the wire. Depending on the local resistivity value and the distance d, the propagation velocity may change considerably. The predictions of the model are in good agreement with the available experimental data. |
