Diffusion of Magnetic Flux into a Cylindrical Liner in the Limit of High Magnetic Reynolds Number.
Abstract
Calculations have been made of the rate at which confined magnetic flux compressed by an imploding cylindrical liner diffuses into the latter because of finite electrical resistivity. The diffused magnetic field profile and associated magneitc energy and Joule heating are also calculated. In the limit of high magnetic Reynolds number Rm, the skin depth, total diffused flux and associated energy scale like 1/(square root of Rm). It is shown that cylindrical liner motion mitigates the diffusion calculated in slab models, owing to the reduction in the surface area through which the flux must diffuse. The influence of the form of the liner trajectory on the results is displayed.
