Model analysis of the Rayleigh-Taylor instability in a shell
Abstract
The development of the Taylor instability in a spherical laser target for nuclear fusion is studied by considering the motion of a shell of zero thickness under various types of perturbations. For a shell under pulsed symmetric perturbations, a condition for the formation of a drop is found. The evolution of a shell under screw and flute instabilities is also described by a two-dimensional equation. The case of a flat film subjected to pressure pulses, whereby a square or hexagonal lattice is formed, is also studied, and it is found that drops form on a hexagonal lattice twice as fast as on a square one.
