Low Frequency Instability of Liquid Liner Implosions Driven by Multiple Free Pistons.

Abstract

The Rayleigh-Taylor instability is studied for an unstable interface composed of rigid finite elements. For wave lengths associated with the finite element scale size the classical Rayleigh-Taylor growth rates obtain. Wave lengths which are short compared with the element scale size are constrained by the rigid finite elements. The consequences of this behavior are discussed with respect to captive liner configurations for imploding liners. (Author)
