Changes in Electrokinetic Coupling Coefficients of Granite under Triaxial Deformation
Figure 2
An example of measurement using the sinusoidal oscillation method. Upstream and downstream fluid pressure are shown as orange and green lines, respectively. In this example, electric current measured using stainless-steel end plugs equipped at each end of specimen as electrode is also shown (blue line). The streaming current coefficient is calculated from the amplitude of fluid-pressure difference () and the amplitude of the electric current.
