Abstract

[Turbulence in convectively unstable shear flows subjected to extrinsic dynamics results from amplification of their perturbations, which are generated by external disturbances and usually start to grow far upstream of the turbulent flow region. In the previous chapters, we considered consecutively the transitional events in far-field and near-field regions of disturbance sources and emphasized the importance of the regions for different laminar–turbulent transition scenarios. Now we concentrate on the disturbance excitation in shear layers. This process is referred to as ‘receptivity’ and is the main concern in this chapter.]
