Propagation of Pore Pressure and Stress in Saturated Porous Media Based on a Darcy-Brinkman Formulation

Figure 5

Normalized amplitude of pore pressure and stress wave versus travelling distance, (a) comparison of Darcy’s law with the Darcy-Brinkman law for an angular frequency of 1000 Hz, and (b) based on the Darcy-Brinkman effect with angular frequency as a parameter for . The solid line denotes the transfer function of the pore pressure, and the dash-dot line represents the transfer function of the stress. The wave travelling distance is normalized by the viscous penetration length at frequency of .
