Calorimetric study of thermal properties of superconducting tapes: experimental method and simulations
Cave, Benoit des Ligneris Marcel Aubin Julian
Original · EN
The method consists in the monitoring of the temperature variation of a superconductor tape subjected to a trapezoidal current pulse. Simulations of the experiment were performed using the lumped capacitance model and also the finite element method. The former reproduces the sample's reaction for the increasing and decreasing parts of the pulse. The same can be said for the finite element method but the decreasing temperature as expected is not adequately reproduced. Treating the problem in two dimensions rather than one should correct the situation. Nethertheless we obtained a thermal conductivity consistent with the literature.
