Turbulence – flame interactions in lean premixed hydrogen : transition to the distributed burning regime

Abstract

The response of lean (φ 0.4) premixed hydrogen flames to maintained homogeneous isotropic turbulence is investigated using detailed numerical simulation in an idealised three-dimensional configuration over a range of Karlovitz numbers from 10 to 1562. In particular, a focus is placed on turbulence sufficiently intense that the flames can no longer be… (More)
