influence on the said processes. In this study, we look at the interaction of non-reacting swirl flows. In particular, the focus is on how the coherent structures associated with the self-excited helical instability of the swirl flows is modified when two swirling jets are placed close to each other. We also look how vortical fluctuations induced in the jets with the introduction of acoustic forcing interact. Time-resolved Schlieren imaging is employed for the experiments and the obtained sequence of Schlieren snapshots is analysed via statistical tools to extract coherent flow structures and to study their interaction.
