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.
