Off topic, but if you're interested in fluid simulations and want to learn more about how they are actually made, John D Anderson's book on Computational Fluid Dynamics is worth working through. It's been quite some time but I remember going through it in Matlab to make small, numerical simulations in the book. The problem with fluids is that it's a very complex branch of physics with many gotchas and many difficulties that you must navigate through, often blindly, to get a reasonable approximation to a solution. The fluids specialists I worked with on the past almost always needed actual physical tests to prove out their engineered designs, rework simulations, etc.
