Abstract

Wave propagation in a porous column consisting of sand particles is studied by means of a shock-tube technique. Experimental results are presented for both air and water as pore fluids. Quantitative information on pore-pressure amplitudes, wave speeds, and damping is compared with theoretical predictions. Good agreement is obtained for the air-filled pores. For the water-saturated pores the two-wave structure is observed, and the corresponding pressure-amplitude ratio is consistent with the observed first-wave speed. The transient permeability is approximately one-third the steady-state value. Added mass is significant.
