With this video, we introduce Turbulence, my favorite topic in fluid mechanics. A flow state characterized by chaos and mess that's literally everywhere in the world. With laminar flows we could make assumptions like steady, fullydeveloped, twodimensional, etc. With turbulence, there are no available assumptions to make the NavierStokes equations easier to work with, and as a result are not solvable.

We will cover (1) why we need to study turbulence; (2) what turbulence is physically; (3) why we can't solve them theoretically; (4) how to know when flow is turbulent; and (5) how to model and analyze turbulence.
