Abstract
In this paper, We introduce model for the LES of lifted non-premixed jet flames based on 2 scalar flamelet modeling. The flamelet G-equation for premixed combustion and the conserved scalar equation for non-premixed combustion are combined to express partially premixed flame propagation. The calculation results are shown that wrinkling lifted flames are simulated and the lift-off height can be predicted. This method will be useful to investigate the flame stabilizing mechanism or flame controls of non-premixed jet flames.
