burgers module¶
Burgers dataset.
This Dataset
contains solutions to the Burgers’ equation with
periodic boundary conditions on the interval \([0, 2\pi]\) for different
time steps:
An analytical expression can be obtained for the solution, using the Cole-Hopf transform:
where \(\phi\) is solution to the heat equation \(\phi_t = \nu \phi_{xx}\).
This Dataset
is based on a full-factorial
design of experiments. Each sample corresponds to a given time step \(t\),
while each feature corresponds to a given spatial point \(x\).
