Fluid dynamicist here.

If I were teaching this I would add the vorticity-streamfunction formulation before "primitive variable" incompressible Navier-Stokes in 2D. ("Primitive variables" include velocity and pressure, and not derived quantities like vorticity or the streamfunction.) It is a more theoretical approach, but it satisfies mass conservation by construction. Satisfying mass conservation in primitive variables for incompressible CFD is more complicated, and is often poorly understood. That's why I'd also have a lecture about mass conservation in the class.

Then again, Prof. Barba probably recognizes this and didn't have the time to cover this in the class.

According to Star Trek history there was a logical progression from Navier-Stokes to the invention of the warp drive, so this should make that a lot easier.

So you are saying we are just one notebook away from warping? Interesting. Its time to pack the bags!

As soon as we solve those pesky turbulence problems we should be good to go

Oh nice, meeting Dr. Yokota again. He was the second advisor for my PhD studies. A great person to talk with, always extremely helpful and engaged - I'm not surprised that he'd be the one coming up with such an easily understandable course.
