Abstract

Some flow, such as laminar separation bubbles, present mechanisms of intrinsic instability that result in the emergence of three-dimensional structures. The threedimensionalization of these flows can amplify external perturbations. The proposal of this project is to analyze the behavior of the perturbations in flows from the analysis of the primary and secondary instability of the separation bubbles.
