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 H-H nanopore (velocity profiles for the 10 nm H-H nanopore are
provided in Fig. S5 in Supporting Information). The flow profiles are
observed to be more complex at all values of saturation and is a
function of the location of the respective phases within the pore.
