New jellyfish flow visualization movie.


After much work Thursday and Friday, we finally got all of the pieces together for our APS DFD gallery of fluid motion entry! You can see the final result here: http://www.youtube.com/watch?v=aNu3ErorsDM

We still need to do some work with the fluorescein, most of the video was over saturated. It's possibly harder to do proper flow visualization with the upside down jellyfish because you can't inject a little cloud of dye for the jellyfish to swim through. Also, the elaborate oral arms do a good job of breaking up the streams of dye.

I'd also like to give a big thanks to Christy Hamlet for making last minute videos of her immersed boundary simulations so that we would have enough footage to complete the video and create a good story line.

I think this video ended up better than our first attempt at the fluids gallery, but we still have some work to do. My goal is to start working on next year's video now (rather than next fall) and perfect all of the techniques.
