Effect of Merging Angle on Turbulent Mixing Layers

Recent Advances in Turbulent Mixing

Experimental, modeling, and direct-numerical-simulation (DNS) studies have advanced our understanding of turbulence and mixing. The mixing transition, that occurs across a broad spectrum of flows, at outer-scale Reynolds numbers in the vicinity of Re δ ≈ 1 − 2 × 10 4 , or Taylor Reynolds numbers of Re T ≈ 100 − 140, will be discussed. Inflow-/initial-condition effects in high-Re shear layers wi...

Eddy Mixing Coefficient On

Data on the composition and thermal structure, and the Lyman-alpha dayglow of Saturn when analyzed in conjunction with photochemical models of the hydrocarbons and the atomic hydrogen g reduction yield the homopause value of the eddy diffusion coefficient to be approximately 10 cm2 s-l. The equatorial value of the eddy diffusion coefficient at the homopause of Saturn is thus found to be approxi...

Subgrid models in turbulent mixing

We are concerned with the chaotic flow fields of turbulent mixing. Chaotic flow is found in an extreme form in multiply shocked Richtmyer-Meshkov unstable flows. The goal of a converged simulation for this problem is to obtain converged solutions for such micro solution features as the joint probability distributions of the temperature and species concentration, as well as the macro features su...

Turbulent mixing and beyond.

Turbulence is a supermixer. Turbulent mixing has immense consequences for physical phenomena spanning astrophysical to atomistic scales under both high- and low-energy-density conditions. It influences thermonuclear fusion in inertial and magnetic confinement systems; governs dynamics of supernovae, accretion disks and explosions; dominates stellar convection, planetary interiors and mantle-lit...
