Fig. 9 Water and hydrocarbon velocity profiles at 0.002 nm/ps2 in 15 nm HH pores. The flow profiles for both phases appear more complex and simply correspond to the local phase densities within the pore.
Fig.10 shows the velocity profiles in a 5 nm, 10nm and 15nm HH pore with a water concentration of 71.43%. The peaks and the troughs in the velocity profiles correspond to the local density of the water and hydrocarbon phases within the pore.
