Abstract

Any realistic disturbance in a flow field is of limited spatial extent. During the last 10-15 years considerable progress has been made in the understanding of the physics of locally excited disturbances in unstable flows. Theoretical, experimental and numerical work has contributed to this progress. First, the aim of the colloquium was to summarize the state of the art knowledge in the field of wave packet dynamics including the three-dimensional compressible, and non-linear theory and extensions to nonlinearity as well as experiments and numerical simulations. Further the colloquium was intended to show how the developed theory of localizeddisturbances can be used in applied engineering problems. The role these disturbances play in the framework of transition to turbulence, active flow control etc. were to be discussed.
