...-linearity in flow that occurs when the Reynolds number exceeds its critical value. This paper presents a non-linear model for flow in two-dimensional rock fractures based on a second-order perturbation solution to the two-dimensional Navier-Stokes equations under the pressure boundary condition. The effects...
