A neural network architecture and training algorithm to predict viscoelastic stresses from vortical data

Numerical simulations of elastic turbulence in parallel shear flows of polymer solutions indicate that the phenomena is associated with the formation and instability of exact coherent states dominated by thin sheets of polymer stress. However, these ``arrowhead''structures are yet to be seen directly in experiments, wh...

Learning dynamically consistent flow reconstructions from limited observations

Trajectory-Consistent Network Training (TraCTra), a label-free framework that trains reconstruction networks using only partial observation sequences and a differentiable forward model, establishes trajectory consistency as a general supervision principle for reconstructing hidden dynamical states without full state tr...
