【Abstract】

<正>Locally perturbing a parallel shear flow induces a spatially localized patch of turbulence that slowly invades the surrounding laminar flow.Though spatio-temporal patterns such as these "turbulent spots" play a crucial role in transitional flows,the mechanism which gives rise to the observed localized structures is not well understood.We will present evidence that a well-developed theory of a localized patterns in simpler PDE models carries over to
