Abstract

The Sydney swirl burner non-reaction case was studied using large eddy simulation. The two-point correlation method was introduced and used to estimate grid resolution. Energy spectra and instantaneous pressure and velocity plots were used to identify features in flow field. By using these methods, vortex breakdown and precessing vortex core are identified and different flow zones are shown.
