What is it about?
The dynamics of the flow structure of two turbulent planar opposing impinging jets confined in a open cubical subjected to external lateral flow is studied experimentally. Results show that the flow fields can exhibit self-sustained oscillations, and we analyze the effects of the confinement boundaries and the interactions between the jets and the crossflow on the spatio-temporal dynamics of the flapping flow.

Why is it important?
We analize the pronounced 3D flapping motion of the confined impinging jets and discuss potential applications related to heat transfer enhancement.
Perspectives
