Abstract:
A multilayer liner made of a composition of two materials with different conductivities is considered. The fractions of the components in the layers are varied so that the effective conductivity increases in the direction of magnetic-field diffusion under a special law that allows one to obtain an analytical solution. It is shown for a particular example that using a temperature criterion taking into account the density, heat capacity, and thermal conductivity of the components, it is possible to produce a liner for which the magnetic-field amplitude can be increased by 30% and the velocity and energy can be increased by a factor of 1.6 and 2.7, respectively, compared to the original version of a homogeneous metal liner.
