Abstract

[The ability to observe monochromatic instability waves in laboratory experiments is stipulated by controlled application of special disturbance sources, which excite small-amplitude oscillations at a single frequency with a predominant transverse wavenumber. In contrast, natural disturbances are mostly localized in space and/or time. In such cases, the wave packet concept discussed in this chapter can be used, which appears highly valuable for the general analysis of flow instability properties.]
