In [17]: the Wasserstein gradient flow structure of the PDE system governing multiphase flows in porous media was recently highlighted in [85]. The model can thus be approximated by means of the minimizing movement (or JKO) scheme. We solve the JKO scheme using the ALG2-JKO scheme proposed in [55]. The numerical results are compared to a classical upstream mobility Finite Volume scheme, for which strong stability properties can be established.
