Based on the incompressible Navier-Stokes equations, this dataset contains trajectories starting from sinusoidal vortex sheet initial conditions, see
https://arxiv.org/abs/2405.19101.
It also contains a passive tracer that is carried by the flow.
The assembled NetCDF file has a single variable called velocity with dimensionality
20000 (number of trajectories)
21 (time steps)
3 (horizontal velocity, vertical velocity, passive tracer)
128… See the full description on the dataset page:
