ABSTRACT
The parallel plate model is a commonly used formula for flow simulation through a rough fracture for which an exact solution for hydraulic conductivity is available (Zimmerman& Bodvarssoni 1996). Ignoring the gravity effect, the Cubic Law is expressed as
where Q is the volumetric flow rate (m3/s), h is the distance between parallel plates (m), P is the pressure drop (Pa), L is the distance between the inlet and outlet boundaries (m), and µ is the fluid viscosity (Pa.s).
