Abstract

The fluctuations of the advancing interface observed in experiments on two-phase fluid flow in porous media are investigated using several evaluation techniques. We find that the amplitudes of these fluctuations are distributed according to a power law of the form P(-1)-(+1), with 2.7. Our results together with a recent model of anomalous roughening suggest a plausible explanation for the nonuniversal values of the exponents observed in the experiment on two-phase flow.
