Reading 3.4-3.5

Sweet and Double Sweet.

Finally, we REALLY know what the Reynolds number is! I did not know this day would come! I now know what it would feel like to be free.

Also, boundary layers--how awesome are those? I can't get enough of this. Maybe that's because I can sit back and relax and don't have to worry about the homework, but it seems that all of you are enjoying this too. You should, it's pretty awesome.

Reading 3.2-3.3

Wow. That was sweet. I'm not sure that I have any questions past what has already been written about on the cmfd planet.

I'm just in awe about vorticity. My favorite thing was vortex rings when I was studying dynamical systems: I thought that I could narrow down their creation to be dependent on a few parameters of the vortex ring generator and then discuss their stability with regard to that parameter space. We couldn't. It was hard.

However, I never quite thought about how the vorticity was closing up on itself in a loop, rather than one long thread. If that had been one long thread, where would it have stopped? I don't know what I would have said to that question had I asked it then, but seeing the true result proved in the reading here was awesome.

Also, that shear waves exist but just are too silly to be seen was pretty neat too.
