摘要：

We are interested in identifying the mean-flow correction in the development of an instability. In the presented configuration (a 2D jet confined in a rectangular cavity that presents an oscillating instability), numerical simulations allow the identification of this mean-flow correction. We show that this distortion contributes to the non-linear saturation of the instability and that it is itself generated by the instability development: the action of the Reynolds tensor due to oscillating terms produces the mean-flow change.
