Parallel Flow Instability

Description

This lecture covers the concepts of parallel flow instability, focusing on hyperbolic tangent and broken-line profile mixing layers. It explains the velocity ratio effect, temporal and spatial approaches, and solving the Rayleigh equation for real k and complex w using finite differences. The instructor demonstrates the stability analysis and the separation of spatial waves into k+ and k- waves by adding a positive imaginary offset to the frequency.
