1- And 2-D Numerical Simulations Of Spherical Pinches

Abstract

play a n important roll in the later stages of implosion as the liner appears to break up into a stack of axially separated disks. It is suggested that this instability is excited by azimuthally symmetric striations in the solid bulk of the liner formed by int,eraction with the R-T “troughs” of the liquid phase. Such striations, interpreted as such, have been observed in meteors. Observed mode dominances are interpreted as resulting from electrical resistivity and visrosity. The validity of treating the solid phase as a highly viscous fluid subject to a c m wavelength R-T instability is discussed.
