Description
Summary:The evolution of a spherical temperature pulse in a three-dimensional medium modelling a dense winding prepared from a copper stabilized high temperature superconductor composite is calculated numerically. Non-monotonic behaviour of the temperature distribution characteristic radius, r 1/2, over time is observed. The reduction in the r 1/2 value correlates with the drop in the medium's heat conductivity with temperature.
