tortuosity_fd#

tortuosity_fd(im, axis)[source]#

Calculates the tortuosity of image in the specified direction.

Parameters:
  • im (ndarray) – The binary image to analyze with True indicating phase of interest

  • axis (int) – The axis along which to apply boundary conditions

Returns:

results – The following values are computed and returned as attributes:

Attribute

Description

tortuosity

Calculated using the effective_porosity as \(\tau = \frac{D_{AB}}{D_{eff}} \cdot \varepsilon\).

effective_porosity

Porosity of the image after applying trim_nonpercolating_paths. This removes disconnected voxels which cause singular matrices.

original_porosity

Porosity of the as-received the image

formation_factor

Found as \(D_{AB}/D_{eff}\).

concentration

An image containing the concentration values from the simulation.
