WebIn-plane permeability can be measured by two methods: unidirectional i.e. channel flow method and two-dimensional i.e. radial flow method. The latter is preferred due to the fact that it can determine not only the principal direction but also the principal values of permeability tensor in the plane direction at the same time.
