My suspicion is fluid dynamics is fundamentally chaotic, but that even with a steady, even and predictable flow, if even possible, the motion of the wheel would still be chaotic and that there is little relation between the chaos of the fluid and the chaos of the wheel movement. That's just what I think, so, take with a grain of salt, I honestly do not know. btw, chaotic does not mean erratic nor does it mean random, but instead Chaos Theory states that within apparent randomness of a complex system there are underlying mathematical patterns driven by a perpetuating feedback and resulting in a self-similarity transcending scale, as well as self-organization (fractals), and that deterministic non-linear systems are subject to a sensitive dependence on initial conditions (aka butterfly effect). I also think this is not really an experiment but merely a physical demonstration of Chaos Theory.
