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.
