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