Permeability tensor rotation

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) ).
