Abstract
Numerical simulations for Rayleigh-Taylor (RT) and Richtmyer-Meshkov (RM)
instabilities for three dimensional axisymmetric fluids have been successfully con-
ducted by a front tracking method. In the first simulation, we consider single mode
RT instability for an axially symmetric perturbed interface in a circular tube. We
compare the computed bubble velocity with theory and laboratory experiment and
find excellent agreement. The second simulation studies the RM instability for an
axisymmetric sphere driven by an imploding shock. We investigate the growth rate
of perturbation, the reshock process and the phase inversion phenomenon.
1 Introduction
The evolution of Rayleigh-Taylor (RT) and Richtmyer-Meshkov (RM) instabilities
has been the focus of investigations for many
