This Letter reports the first large eddy simulation of a turbulent flame using lattice-Boltzmann model. To that end, bluff-body stabilized propane–air is carried out, showing an agreement similar to those available in literature. Computational costs are also reported, indicating modeling reactive flows competitive, with around 1000cpuh required simulate one residence time 1.5 m burner.

The physical nature of the initial transition to three-dimensionality of #ow past a circular cylinder has been the subject of considerable debate in the literature. Of several proposed mechanisms, the possibility of classi"cation as an elliptical instability is re-examined in this article. Detailed Floquet analysis of the transition shows clear evidence of the growth of an elliptic instability ...
