Abstract EN
The knowledge of flow phenomena in fractured rocks is very important for groundwater-resources management in hydrogeological engineering.
The most commonly used tool to approximate the non-Darcy behavior of the flow velocity is the well-known Forchheimer equation, deploying the “inertial” coefficient β that can be estimated experimentally.
Unfortunately, the factor of roughness is imperfectly considered in the literature.
In order to do this, we designed and manufactured a seepage apparatus that can provide different roughness and aperture in the test; the rough fracture surface is established combining JRC and 3D printing technology.
A series of hydraulic tests covering various flows were performed.
Experimental data suggest that Forchheimer coefficients are to some extent affected by roughness and aperture.
At last, favorable semiempirical Forchheimer equation which can consider fracture aperture and roughness was firstly derived.
It is believed that such studies will be quite useful in identifying the limits of applicability of the well-known “cubic law,” in further improving theoretical/numerical models associated with fluid flow through a rough fracture.
