Abstract
The nonlinear evolution of large structure in Rayleigh-Taylor and Richtmyer-Meshkov bubble and spike fronts is studied numerically and explained theoretically on the basis of single-mode and two-bubble interaction physics at Atwood numbers (). Multimode Rayleigh-Taylor bubble (spike) fronts are found as [] with , while Richtmyer-Meshkov bubble (spike) fronts are found as () with at all . The dependence of these scaling laws and parameters on and on initial conditions is explained.
