Fig. 8 Distribution of water molecules for various water
concentrations. Hydrocarbon is not shown. On the left, Cw = 18.97% and
on the right, Cw = 71.43%. Increases in water concentration increases
the adsorbed layer thickness that in turn influences water and
hydrocarbon velocities.
Fig. 9 shows the water and hydrocarbon velocity profiles at a higher
value of acceleration of 0.002 nm/ps2 in a larger 15
nm HH nanopore (velocity profiles for the 10 nm HH nanopore are provided
in Fig. S5 in Supporting Information). The flow profiles are is observed
to be more complex at all values of saturation and is a function of the
location of the respective phases within the pore.
