Cool. Or maybe use machine learning to invert the low-dimensional description of the phenomenon..

Oh, and there's also https://arxiv.org/abs/2211.00771. So you put your fluid in a cubic reservoir with a vortex ring gun at each corner of the cube aimed at the center of the cube. You can make free floating blobs of turbulence in the center of the reservoir by shooting combinations of vortex rings. Vary the combinations of vortex rings and you vary the properties of the turbulent blob. So for whatever varieties of turbulence you can synthesize and instrument, you now have an analog computer for finding properties and calibrating your digital simulations. -- rec --
