... the flow problem in an axisymmetric non-uniform grid. The new scheme is derived by performing a fourth-order finite difference approximation for the spatial derivatives of the axisymmetric fluid-diffusion equation in a non-uniform grid configuration. The implicit Crank-Nicolson technique is then applied...

... Abstract Too many required pre-existing fractures (over fifteen) by the HTPF method restrict the wide application under various stress measurement conditions. Considering the shortcomings of HTPF method, a rock mechanics equation to describe the shearing stresses intrinsically present...

...-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...
