TLDR
In this paper, the authors considered the propagation of a pressure wave through an imploding liquid metal liner near turnaround, due to the compression of magnetic flux and plasma, based on which the pressure distribution near turnaround was derived analytically under the assumption of a small Mach number M (defined by the ratio between characteristic radial velocity of liner and the velocity of sound through the medium).Abstract:
The propagation of a pressure wave through an imploding liquid metal liner near turnaround, due to the compression of magnetic flux and plasma is considered, based on which the pressure distribution near turnaround is derived analytically under the assumption of a small Mach number M (defined by the ratio between characteristic radial velocity of liner and the velocity of sound through the medium). It is shown that under certain conditions, the rarefaction wave from the outer (free) surface causes the apparition of a negative pressure in the imploding liner, with consequent liability of cavitation. The criterion for the generation of the negative pressure is found to be MΛ0.6~0.7 for the range of parameters considered (A: liner thickness at turnaround normalized by the inner radius).read more

Cavitation in Cylindrical Liquid Metal Shell Imploded for Axial Magnetic Flux Compression
TL;DR: In this paper, the cavitation in a cylindrical liquid metal shell (liner) imploded to a trapped magnetic field is discussed on the basis of the one-dimensional treatment of compressible fluid dynamics including the effect of the diffusion of magnetic field into the liner.

Theoretical studies of the formation and adiabatic compression of reversed-field configurations in imploding liners
TL;DR: In this article, the formation and compression of e-beam-induced reversed-field theta-pinch configurations were studied theoretically in an MHD treatment, taking into account classical collisional resistivity plus anomalous resistivity derived from microinstabilities.
