This lecture covers the concept of Kelvin's wake created by a ship, the generalized group velocity, and the absolute/convective instability theory in fluid dynamics. It delves into the analysis of linear impulse response, complex Fourier space criteria, and the application to mixing layers. The lecture also discusses the behavior of cylinder wakes at different Reynolds numbers, the bluff body wake as a flow oscillator, and the instability in parallel wakes. Furthermore, it explores the local instability behavior of cylinder wakes and 2D parallel flow concepts.
