Uncertainty Quantification for Turbulent Mixing Flows: Rayleigh-Taylor Instability
[chapter]
2012
IFIP Advances in Information and Communication Technology
Uncertainty Quantification (UQ) for fluid mixing depends on the length scales for observation: macro, meso and micro, each with its own UQ requirements. New results are presented here for macro and micro observables. For the micro observables, recent theories argue that convergence of numerical simulations in Large Eddy Simulations (LES) should be governed by space-time dependent probability distribution functions (PDFs, in the present context, Young measures) which satisfy the Euler equation.
