Asymmetry of the normal zone propagation velocity in superconductors
نویسندگان
چکیده
in superconductors, relative to the direction o f the transport current is suggested. The difference o f the normal-superconducting interface velocities parallel and anti-parallel to the current direction due to this mechanism is o f the order o f 1 50 cm s 1 for different metals. The thermoelectric effect (Thomson heat) has a hysteresis which occurs opon destruction (or restoration) o f superconductivity in the sample with respect to the transport current.

Normal zone in large composite superconductors*
This paper considers the nucleation and propagation of a normal zone in large composite superconductors, considering the relatively tong time of current redistribution in the stabilizer. A model is proposed for treating the composite as an effective electrical circuit, which yields two diffusion equations for the electric current and the temperature distributions along the conductor. Numerical ...
متن کاملPropagating normal domains in large composite superconductors
We study the nucleation and propagation of the normal zone in large composite superconductors, considering the relatively long time of current redistribution in the stabilizer. We propose a model treating the composite as an effective electrical circuit, which yields two diffusion equations for the electric current and temperature distributions along the conductor. Numerical simulations are per...

In this investigation, the structure of one-dimensional flame propagation in uniform cloud of volatile organic particles has been analyzed in which the structure of flame is divided into three zones. The first zone is preheat zone which is divided into three subzones itself. In first subzone (heating), particle cloud heated until the moisty particles reach to vapor vaporization temperature. In ...

متن کاملPropagation of the normal zone in composite superconductors with high contact resistance
The propagation of the normal zone in composite superconductors with high thermal resistance and high electrical contact resistance between the superconducting and the normal components of the conductor is analysed. It is shown that in certain conditions propagation can result from successive multiple splittings of the resistive domain generated. The minimum initiation current of this process h...
