Abstract

A new scientific approach to subgrid scale modeling is presented for chaotic problems involving a high degree of mixing over rapid time scales. Richtmyer-Meshkov unstable flows are typical of such problems. Chemical reaction rates for turbulent mixtures are shown to converge with feasible grid resolution. The essential dependence of fluid mixing observables on transport phenomena is observed.
