This lesson covers the concept of turbulence in 2D flows, focusing on conservation laws, Kraichnan theory, and the subtleties and fluxes in numerical results. It explores the real-world applications of 2D flows, such as in astrophysics and atmospheric flows, and discusses the formation of structures in 2D flows. The lesson also delves into the conservation laws of energy and enstrophy, and the role of vorticity in 2D flows. It further explains the concept of fluxes, particularly energy flux and enstrophy flux, and their implications in steady flows. The lesson concludes with a discussion on Kraichnan theory and its application in understanding the behavior of kinetic energy and enstrophy in 2D flows.

- Conservation laws play a crucial role in understanding 2D flows.
- In 2D flows, both energy and enstrophy are conserved.
- Vorticity in 2D flows does not increase or decrease, but is advected.
- Fluxes, particularly energy flux and enstrophy flux, are important in understanding the behavior of 2D flows.
- Kraichnan theory provides insights into the behavior of kinetic energy and enstrophy in 2D flows.
