Characteristics

Abstract
We numerically simulate the previous instability experiments of a double mode
perturbed interface in the initial nonuniform flows in an unreshocked case, the
numerical results are in very good agreement with the experiment, meanwhile
investigate the effect of the nonuniformity of flows on the evolution of instability
in nonlinear regime after reshock, by adopting two different nonuniform
coefficients (δ1=0.6162, and δ2=0.4961) in the Gaussian distribution of the
initial nonuniform density. The results indicate that the nonuniformity of
the initial flow has great effect on the evolution of instability in the linear and
weak nonlinear regime prior to reshock.
Keywords: nonuniform flows, Richtmyer-Meshkov instability, mixing, reshock.
