The instability of fronts in a porous medium
Copyright policy )The instability of fronts in a porous medium
We use a random choice numerical method to analyze the instability of a front separating two fluids in a porous medium. We observe a linear instability and a catastrophic finite amplitude instability. A qualitative analogy with problems involving a transition to turbulence is pointed out.
