ABSTRAKT
Large Eddy Simulation is used to investigate the flow field of a turbulent jet emerging into a laminar crossflow. In the jet, swirl is introduced by means of body forces with swirl number up to S = 0.6 in the pipe. The impact of the jet swirl on the flow field and in particular on the mixing is investigated by means of various analyses. It turns out that the resulting flow and concentration fields are substantially distorted by the swirl but the overall mixing as determined by cross-sectional spatial and temporal mixing indices is only little influenced.
