Diffusive transport of mass occurs at small scales in turbulent premixed flames. As a result, multicomponent diffusion, which is often neglected direct numerical simulations (DNS) combustion, has the potential to impact both turbulence and flame characteristics scales. In this study, we evaluate these impacts by examining enstrophy dynamics internal structure for lean hydrogen-air neglecting se...

Analytical and numerical investigations were performed to study the influence of Soret Dufour effects on double-diffusive convection in a vertical porous layer filled with binary mixture subject horizontal thermal solute gradients. In particular, was focused effect diffusion bifurcation types from rest state toward steady convective state, then oscillatory state. The Brinkman-extended Darcy mod...
