Preferential diffusion effects in LES of mild combustion with flamelet generated manifolds

, 2015
Preferential diffusion effects are investigated in flame stabilization of turbulent lifted flames using LES with a FGMPDF model. The experimental test case is the Delft JHC burner in which methane based fuel has been enriched with various amounts of H2 ...

Extension of the FGM technique for autoignition and preferential diffusion effects [PDF]

, 2015
Flamelet Generated Manifolds (FGM) has been extended to account for preferential diffusion effects and autoignition. Such development is made in order to study stabilization mechanism of turbulent lifted CH4/H2 flames of the Delft JHC burner.

Diffusion controlling porphyrin assembled structures

, 2016
Here we report a mechanistic study on the diversity of assembled structures. We take the assembly of porphyrin molecules as an example to investigate how the diffusion of molecules influences the structure of assemblies.

Influence of preferential diffusion in turbulent lean premixed hydrogen-rich syngas spherical flames at elevated pressure

, 2015
The objective of this work was to investigate the influence of preferential diffusion on flame structure and propagation of lean-premixed hydrogen-carbon monoxide syngas-air flame at elevated pressure using direct numerical simulation (DNS) and detailed ...

Anelastic relaxation due to interstitial solutes diffusion in Nb and Nb-1 wt% Zr

, 2006
Metals and alloys containing solute atoms dissolved interstitially often show anelastic behavior due to a process know as stress-induced ordering. The application of mechanical spectroscopy measurements to diffusion studies in body-centered cubic metals ...

FGM modeling considering preferential diffusion, flame stretch, and non-adiabatic effects for hydrogen-air premixed flame wall flashback

Preferential diffusion plays an important role especially in hydrogen flames. Flame stretch significantly affects the flame structure and induces preferential diffusion. A problematic phenomenon occurring in real combustion devices is flashback, which is
