The authors extend previous work on instability growth in spherically converging layered fluid systems by characterizing linearized perturbation dynamics on the collapse of a spherical gas cavity surrounded by an incompressible fluid. They also investigate energy damping mechanisms related to fluid compressibility. Numerical examples are presented where water at STP initially surrounds a gas cavity filled with low pressure air. This work is of interest to the weapons community.
