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 (A). Multimode Rayleigh-Taylor bubble (spike) fronts are found as hB=BAgt2 [hs=s(A)gt2] with B=0.05, while Richtmyer-Meshkov bubble (spike) fronts are found as hB=aBtB (hs=asts(A)) with B=0.4 at all A's. The dependence of these scaling laws and parameters on A and on initial conditions is explained.
