Taylor couette flow
Taylor Couette flow is a spatiotemporal ordered flow contained in a gap between two concentric rotating cylinders. Increasing the angular velocity of the inner cylinder, we see that the flow pattern becomes unstable and collapses. This process shows a scenario in which an ordered flow becomes turbulent, and which has been theoretically studied and described as ” a route from T3 to Chaos”. T3 means 3 independent ordered periodic flow and chaos is an disordered state defined mathematically.

This installation is a real fluid mechanics machine that realizes the Taylor Couette Flow. However, the scenario isn’t verified 100 %. Ruelle and Takens have claimed that when T3 appears, a Chaotic state immediately takes over. But this claim is not consistent with the simulation results as we have stable T3 regions. On the other hand, it is very hard to detect the T3 motion. Empirically we only observe T2 instead.
Therefore, we generate T1, T2, T3 and Chaos in computer simulations and use their motion structure to make holophonic sounds. We expect the audience to experience the scenario, which is visually impossible but acoustically possible. The sound pattern with the holophonics is generated by the famous chaos mapping called the logistic map.
