Experimental measurement of the porosity and the viscous tortuosity of rigid porous material in low frequency
In this paper, an acoustic method is presented for measuring the porosity and the viscous tortuosity of air-saturated-porous materials at low frequencies. The proposed method is based on a temporal model of the direct and inverse problem for the reflection of low-frequency waves by homogeneous isotr...
