This paper analyzes turbulence-chemistry interactions of an n-dodecane-air flame, focusing on the degree to which flame structure and fuel oxidation pathways change in turbulent flames relative to their corresponding laminar flames. This work is base

An empirical characteristic scaling model for freely-propagating lean premixed hydrogen flames

Lean premixed hydrogen flames are thermodiffusively unstable due to the high mobility of the fuel, which leads to localised acceleration and thinning of the flame. Consequently, the one-dimensional steady unstretched laminar flame speed and thermal t

Turbulence-chemistry interaction in lean premixed hydrogen combustion

Autor: John B. Bell, Marcus S. Day, Andrew Aspden

Publikováno v: Proceedings of the Combustion Institute. 35:1321-1329

This paper presents three-dimensional direct numerical simulations of lean premixed hydrogen flames at an equivalence ratio of varphi=0.4 over a range of turbulence levels from Ka=1 - 36. The simulations form part of a larger effort to construct a DN

Knowledge of the fractal properties of premixed flame surfaces can potentially be used to help develop turbulent combustion models. Here, direct numerical simulations of low Damkohler number flames are used to analyse the fractal nature of the flames
