porespy.beta.df_to_tortuosity

porespy.beta.df_to_tortuosity(im, df)

Compute the tortuosity of a network populated with diffusive conductance values from the given dataframe.

Parameters:

• im (ndarray) – The boolean image of the materials with True indicating the void space

• df (dataframe) – The dataframe returned by the blocks_to_dataframe function

• block_size (int) – The size of the blocks used to compute the conductance values in df

Returns:

tau – The tortuosity in all three principal directions

Return type:

list of floats
