Experimental Study of Dynamic Permeability in Porous Media

Abstract

We report experimental measurements of ac permeability made on a variety of fused glass beads and crushed glass in a frequency range of 0.1 Hz to 1 kHz. We observe a rollover in $\ensuremath{\kappa}(\ensuremath{\omega})$ from a viscous flow regime to an inertial one, and determine the values of the transport coefficients in both the high-frequency limit and the low-frequency limit. A good agreement is found with the scaling theory $\frac{\ensuremath{\kappa}}{{\ensuremath{\kappa}}_{0}}=f(\frac{\ensuremath{\omega}}{{\ensuremath{\omega}}_{c}})$ with only two independent parameters.
