Abstract

The formulation of a general method is presented for the stability analysis of the spherically shaped surface of a gas bubble inside a thin, finite, incompressible liquid layer of a ternary D-T mixture as found in a spherical cryogenic inertial confinement fusion target. A force balance on the liquid-vapor interface is performed to find the initial surface-tension gradient required to hold the liquid layer uniform. A node centered, finite volume, central difference formulation is then used to solve numerically the transient continuity, Navier-Stokes, and energy equations in the presence of a variety of nonaxisymmetric perturbations. The approach used in establishing the appropriate numerical procedures is described.
