Claims

C1strongest claim

The combination of Maxwell--Stefan diffusion and dynamic capillarity renders transport pseudo-parabolic, resolving the loss of strict hyperbolicity that plagues three-phase Buckley--Leverett and ensuring a well-posed initial-value problem.

C2weakest assumption

That the added physics (dynamic capillarity, Maxwell-Stefan diffusion, inertial damping) can be incorporated while preserving an exact fractional-flow decomposition of phase velocities and a single global-pressure equation that drives the total Darcy flux.

C3one line summary

A global-pressure formulation for multicomponent flow in fractured media incorporates dynamic capillarity and Maxwell-Stefan diffusion to produce pseudo-parabolic transport that resolves hyperbolicity loss in three-phase Buckley-Leverett models.
