WebJan 1, 2013 · Therefore, the original permeability tensor can be transformed by rotating the original xOy coordinate to a new ξ O η coordinate according to tensors' characteristics [ 19 ]. The angle between the ξ O η coordinate system and the xOy coordinate system is represented by the angle α ( Figure 1 (c) ). Webpermeability tensor is therefore needed in modeling flow in anisotropic medium. In this research, two widely used finite volume schemes, Two-Point Flux Approximation (TPFA) …
