Weakly Nonlinear Analysis of a Localized Disturbance in Poiseuille Flow

In this article, we investigate, via a perturbation analysis, some important nonlinear features related to the process of transition to turbulence in a wall‐bounded flow subject to a spatially localized disturbance that is harmonic in time. We show that the perturbation expansion, truncated at secon...
