Figure 5.10: Scatter diagram of velocities vs. pore throat radius in (a) the
regular pore network and (b) within the MDPN model. Direction number 1
is shown using (red) dots, where (blue) squares and (black) circles are used to
show directions number 2 and 3, respectively. To keep the figure less crowded
we have only shown scatter diagram of velocities in directions number 1, 2 and
3 of MPNM.
5.4.2.1 Generic pore networks
We constructed three networks of size N i = N j = N k = 20, which results in
8,000 lattice points for each network. The pore size distributions were presented
